Pertwee, Jon: Who Is The Doctor - UK - Array - Purple Records PUR 111 - original Purple Records release from 1972 - c/w 'Pure Mystery' - This exceptional track was written and released as though it were a Deep Purple single, and is the only Doctor Who tribute track to star an in-character Doctor. Over a prog-rock arrangement of the Doctor Who theme, the Doctor tells us how completely brilliant he is in booming, echoing tomes - the first time that the theme tune had been given lyrics (of sorts)! A 1983 re-issue celebrated the series' Twentieth Anniversary (alongside re-issues of Bullamakanka's Doctor Who is Gonna Fix It and Peter Howell's K9 & Company) with an edited soundtrack suite from The Sea Devils on the B-side (lifted from the successful BBC Records LP Doctor Who - The Music), and a second re-issue appeared on the Safari label in 1985.
