GEORGE Harrison may have been part of the world's most famous pop band, but he often said he had not sought fame or riches.

Indeed, among the Fab Four he was the one who first saw the value of exploring his spiritual side.

He once reflected on his search, saying: "When you've had all the experiences - met all the famous people, made some money, toured the world and got all the acclaim - you still think 'is that it?'.

"Some people might be satisfied with that, but I wasn't and I'm still not."

So, while The Quiet One, as he was known to the tabloids of the 1960s, may have made an impact by writing some of the group's most beautiful songs - Something, Here Comes The Sun and While My Guitar Gently Weeps - perhaps he made his greatest mark on the world by organising The Concert for Bangladesh in 1971.

The idea was to raise cash to ease the humanitarian disaster unfolding in the east of the Indian sub-continent, where a military crackdown had been ordered in East Pakistan, causing 10 million refugees to spill over the border.

Harrison convinced Ringo Starr, Eric Clapton and Bob Dylan to perform at the show, in Madison Square Gardens, New York.

The event raised $243,418 for the United Nations Children's Fund - then a gigantic sum - to help youngsters in Bangladesh.

It also set a standard of caring which, in the middle of the 1980s, saw rock's aristocracy come together for Live Aid and Band Aid.

George Harrison may have been a fine songwriter, but he was an even greater humanitarian.
