+1 for your comment on John Peel
@valiant66.
He helped many young artists to get started by giving them airplay when nobody else had even heard of them.
Some of the artists whose music was first played by Peel, include:
The Ramones
Roxy Music
The Smiths
The Fall
Rod Stewart
T Rex
This article from 'The Guardian' newspaper gives a flavour of his influence on music.

He also hosted the legendary 'John Peel Sessions' where bands played live.
Notable performances included Led Zeppelin in 1969!
Another DJ who I really like and who started out on Radio Caroline, is Johnnie Walker.
He still hosts a programme on BBC Radio 2 called 'Sounds of the 70s' which is brilliant.

His knowledge of both the music, and artists, from that decade is incredible.
