Petula Clark started on BBC radio in the early '40's aged about 8, was in films 40's/50's, had her first hit record early 50's and still singing I believe. G.H.Elliott made his first recording in 1904 and his last just before he died in 1969. Albert Whelan a year longer, first 1903 and last 1969. Both these artistes were well established on the Music Halls before they recorded.
