First of all, I¡¯d like to thank so many readers for your kind messages to me over the past two months. I raise a toast to all of you.

After the operation in November, although the doctors said my cancer was all gone, I wasn¡¯t much interested in food and was steadily losing weight. That was great on the knees, but I got a bit concerned after I¡¯d shed 22 kilograms with no sign of stopping.

Then over New Year¡¯s, I said to heck with it and broke out a bottle of the single-malt whisky I¡¯d been invited to make a cask of to my own recipe at the Nikka Distillery in Yoichi, Hokkaido, in 1986, and which I named Old Nic¡¯s Dram when it was bottled in 2000.

So I got some Antarctic ice out of the freezer, had a couple of hefty glug-glug-glugs (isn¡¯t the music of a new bottle of whisky being poured a heart-warming sound?), and quietly savored, sip by glorious sip, that peaty, full-bodied spirit with an alcohol content of 58 per cent.

Magically, I woke up the next morning feeling hungry and started nibbling away. With my appetite restored, I gained 4 kilograms in 10 days, and now the doctor says I¡¯m ready for a second round of surgery to reroute my innards back to normal.

When that¡¯s over with, I look forward to walking and working in our woods when spring comes, going to the Arctic again in summer, and cooking lots of feasts for friends and visitors.

While I was in hospital, one of the books I was given was ¡°The Beatles: The Biography¡± by Bob Spitz. The big, heavy tome was awkward to handle in bed, so I didn¡¯t start on it till I got home ¡ª but now I think it¡¯s one of the best modern books I¡¯ve read.

I grew up in Britain at about the same time as John Lennon and Paul McCartney, and like them I loved to listen to Radio Luxembourg, a commercial station that played lots of music disdained by the good old (but rather stodgy) British Broadcasting Corp.

I was born in Wales, but went to school in England where, from an early age, I had singing lessons and was enrolled in the church choir. Like most of my Welsh family I loved to sing, and by the age of 10 I was winning competitions as a boy soprano soloist. My stepfather, who I¡¯ve always thought of as my Dad, came into our life when I was 10. He spent 27 years in the Royal Navy and was of Scottish ancestry, though like the Beatles he was born and raised in Liverpool. Dad had a voice like a foghorn, and Mum and I would be acutely embarrassed when he belted out the seafarers hymn ¡°For Those in Peril on the Sea¡± on the rare occasions he was cajoled into attending church.

That biography vividly brought back to me so many scenes from my own life as a teenager ¡ª but with some very big differences. Unlike John and Paul, I could never get close to mastering a guitar or banjo, let alone the piano in our front room.

Also, unlike John and his friends, I didn¡¯t smoke or pilfer records from shops ¡ª though Mum thought I was gay because I didn¡¯t chase girls and loved writing songs and poetry. The truth was that I was determined to become an Arctic explorer, so I filled my life with weight training, hard cross-country hikes, shooting, kayaking and judo.

Had I met John Lennon back then I doubt we would have got along, because I had a visceral hatred of so-called Teddy boys ¡ª youths, often prone to antisocial behavior, whose greased hair was slicked back to look like the rear end of a duck , and who wore tight ¡°drainpipe¡± trousers, long Edwardian-style jackets and thick crepe-soled boots.

That said, Brian Jones, a founding member of the Rolling Stones, attended Cheltenham Grammar School at the same time as I did. He was one year my junior. He was a fantastic musician, and he once told me he¡¯d like to live for a year with reindeer-herding Lapps and learn their traditional music. Until the drugs and all that nastiness brought him down, he was a highly intelligent and sensitive young man.

Rock ¡®n¡¯ roll hit Britain in a big way, made instantly popular by Bill Haley and the Comets¡¯ ¡°Rock Around the Clock,¡± which topped the charts in 1955. When ¡°Blackboard Jungle,¡± the film in which it featured, came to town, the ushers couldn¡¯t stop the kids dancing in the aisles. It was a riot.

Then of course Radio Luxembourg gave us Elvis Presley, and Britain¡¯s own king of skiffle, Lonnie Donegan. At the time I thought his song ¡°Rock Island Line¡± was the greatest music ever, and I nearly drove my Dad crazy by playing it over and over on the little record player I¡¯d bought in town.

Even though I started writing poems and songs at the age of 14, I didn¡¯t join a band or start recording until I was 37, by which time I was working for the Environmental Protection Service in Vancouver, where I made two friends who would change my life.

One was Adrian Duncan, an EPS engineer who was a brilliant musician and played everything from tuba to penny whistle, banjo to lute; the other was Fred Koch, a waste-disposal expert on contract with the Environmental Protection Service who had a good singing voice and played bass. Together with guitarist Brian Barrington and drummer Ed Cherry, we formed a group called Pacific Rim. I was the lead vocalist.

By that time I had many connections with Japan, and so our group¡¯s first recording contract was with Tokuma Musical Industries, who released a 45 rpm single of two songs I¡¯d written in Japanese that we recorded in Vancouver.

Soon after, we set up a recording studio in Vancouver that we called Bullfrog Recording. It was a small place, but it attracted lots of new and young talent because we could make high-quality demo tapes and call on top-class session musicians.

It was all a lot of fun, but Japan lured me back and since 1978 this country has been my home. Nonetheless, I¡¯ve never severed ties with my Vancouver friends, and we recorded two albums for Toshiba EMI at Bullfrog ¡ª ¡°Sail Down the River¡± and ¡°Whisky.¡±

In Japan in 1979, I came second in the All Japan 17th Yamaha Popular Song Contest with my composition ¡°Ringo no Ki ni Kakurembo¡± (¡°Hiding in the Apple Tree¡°). NHK also used one of my songs, ¡°Na Mo Nai Mizuumi¡± (¡°Nameless Lake¡°), in its regular program ¡°Minna no Uta¡± (¡°Everybody¡¯s Song¡°).

Since then I have sung in dozens of concerts all over Japan, on television and radio, and in 2000 I performed with Adrian Duncan and Fred Koch in a major charity concert at the Budokan in Tokyo. That was a blast!

Songs and singing have always been a part of my life, but expeditions, making a national park in Ethiopia, and a healthy, biodiverse forest here in Nagano Prefecture, have ¡ª together with writing books ¡ª been more to the fore.

However, having a thick plastic tube stuck down my throat for several days in hospital last November, with not a drop of water, let alone good whisky, has left my voice a little raspy ¡ª but friends still urge me to do more concerts.

Making music takes enormous effort and patience, but can be so much fun. Me though, I¡¯ll probably end up like my Welsh grandfather, who once got thrown out of a stuffy English pub for singing ¡ª but not before he mustered his dignity at the door and yelled back: ¡°I¡¯ll have you know I¡¯ve been thrown out of far better places than this!¡±

And he wasn¡¯t even singing one of those naughty rugby songs!
