World Cup Song

I have written the lyrics to a world Cup song for England against an old tune from 1971. Very fast paced northern soul song, which was never a hit in the UK. The vocal was done by an African american group who may well all be dead as may be the songwriter as it was 1971 and I was 16 then
I need someone who can separate the backing track and put down a vocal. I sing it every week whilst out cycling.
I have a track record in these sorts of matters as in 1988 i was the first football fan/ hooligan to write a book about the football terraces that was told would never sell, but it went on to become a best seller and spawned a whole industry as well as Nick Hornby who even mentions me in Fever Pitch. It needs a studio in London or somewhere south of London or someone who knows someone so the track and vocal can be put down. No time wasters from outside England please. More than happy to send the song and the lyrics if you are serious. I need a joint input with myself on the backing vocal.
