The episode of Burke's Law was "Who killed Billy Jo"? The actor who played the unfortunate Billy Jo was Kelly Gordon; according to IMDB Gordon has three acting credits plus one uncredited role. His last apparent role was the murder victim.
So what else did this man do after BL? He was young, only 30 or 31 then.
A search for him leads to a Kelly Gordon in music, both composer and producer. His best-known piece is "That's Life," cowritten with Dean Kay and readily identified with Frank Sinatra's 1966 version.
As a music producer, he is credited with Bobbie Gentry's Ode to Billy Joe. Coincidence? Two "Kelly Gordons"; two "Billy Jo(e)'s"? No - one Kelly Gordon: same dates of birth and death are indicated on imdb and revolvy websites. And, he sang his own song as Billy Jo in Burke's Law.
Gordon died young, so the question about dual Billy Jo/es could only be answered in this life by Bobbie Gentry.
