Tributes are pouring in for the influential DJ John Peel, who has died suddenly, writes Peter Fray in London. British Prime Minister Tony Blair has joined scores of tributes to DJ and broadcaster John Peel, who died after suffering a heart attack on holiday in Peru. Peel, 65, whose career with the BBC's Radio One spanned four decades, is credited with unearthing many of the biggest names in contemporary music and exposing them to record companies and the mass English-speaking audience. They ranged from Pink Floyd and David Bowie to the Smiths and Nirvana. Peel was the first DJ to broadcast the Beatles' Sgt Pepper's Lonely Hearts Club Band and played an important role in breaking several Australian bands in Britain, including the Saints, the Birthday Party and the Go Betweens.
