Thanks for that! It's bugging me now!
Sounds remarkably famiiar.
It actually sounds very similar to the introduction to Roachford's "Cuddly Toy" but that doesn't fit in with anything else you mention.
A few Qs.
I take it you have no real idea when the track is from as you heard it 10+ years ago but if it was on TOTP2 it could have been from much earlier.
Electronic sound/keyboards is mostly early 80s.
Assume it must be fairly obscure if you haven't heard it in the meantime? ie. it also sounds a tad like Soft Cell's Tainted Love but that is played very often so I assume you know it.
Is what you have played the intro or just an extract from the track?
Was it instrumental or did either or both of the two guys sing?
Any description of them? White? Hair - dark or blond, spikey?
Electronic types - Soft Cell, Orchestral Manoeuvres in the Dark, Pet Shop Boys, Howard Jones, Nik Kershaw, A Flock of Seagulls.
