The two stations became uneasy about sharing the same DJ, and eventually Walsh went to BBC Radio London to host the Sunday 7–9 pm show, later adding a second slot on Mondays.
Although he made an impact in the radio world, Walsh will be best remembered for his live work in nightclubs.
His 1987 version of the Fatback Band's "I Found Lovin'" was archetypal of the genre of 'South London Soul'.
Walsh worked with Tony Blackburn[3] to bring soul music to a wider audience, and shortly before his death he co-presented the dance programme Boogie Box on Music Box, alongside Michaela Strachan.
On 29 June 1988, Walsh was injured in a car crash in Ibiza, where he was filming a music video.
