 The theme songs full title was "Angela (Theme from Taxi)", was  written/performed by Bob James and was from his 1978 album  "Touchdown". The title track "Touchdown" was the song Bob had  actually written for the theme, but Taxis producers liked the short  cue Bob had written/recorded for one brief scene with Alex  (Judd Hirsch (qv)) and a young woman, Angela, and used that  instead.
