yeah...pbt (push button technology to give em their full name) are on discogs. http://www.discogs.com/release/463094
It's the B-side of this (untitled) that is the tune you're after.
They were a bradford act and really only people around there know/knew of em. The tune wasnt a big release and is pretty damn hard to get hold of.
If I can find my copy I'll double check the ID for you but I'm pretty certain that this is the tune. Paul Ginetta (prob wrong spelling) made a brief appearance on OSA a year or two ago as PBT so it might be worth sending him a PM?
