This is the song in the closing credits for each of the 7 episodes of Tinker, Tailor, Soldier, Spy which aired on the BBC is 1979. Apparently the singer is Paul Phoenix.

Object now! So this is the new punk-rock.
This goes out to the heroic 80 year old granny objecting to cocks in her changing rooms at her local pool and the legendary lesbians who were banned today from a pride march in Wales for stating "Lesbians Don't Like Penises!"
