Johnnie Walker began his radio career in 1966 on Swinging Radio England, an offshore pirate station, before moving to the legendary Radio Caroline, becoming a household name by hosting a hugely popular night-time show.
After the closure of Radio Caroline [at the time], Johnnie joined BBC Radio 1 in 1969, continuing until 1976 and establishing a reputation as a DJ who prioritised records above chat. On his lunchtime show, which launched in 1971, he pioneered new names like Steve Harley, Lou Reed, Fleetwood Mac, The Eagles and Steely Dan. Pop The Question and Tuesday Chart Rundown were other well remembered features of the show. Following his departure from Radio 1, he moved to San Francisco in 1976, where he recorded a weekly show which was broadcast on Radio Luxembourg.
