Murphy's Mob

I remember this show vaguely. I thought it was about a youth club, i know there was a connection to a football team. Ken Hutchinson (Mac) had another dark secret. He was also an armed robber (pursued by Regan and Carter in The Sweeney 2 movie). Wurzel (the kid with the big nose and strange hair) had to watch his back constantly as his dad was a policeman. I can't remember "Stig" though or what part he played. If the voice behind that awesome theme tune sounded familiar it's because it was sung by the late great Gary Holton of rock band the Heavy Metal Kids. He was a bona fide rock star in his own right but he didn't get real public recognition until he landed the part of cockney ladies man Wayne Norris in Auf Wiedersehen, Pet.
