Van McCoy

He played both. One was to start Radio Ayresome. I'm sure that was The Shuffle, which he talked over and did his introductions.
The other after the match The Hustle.

Or was it the other way round. :ROFLMAO:
Definitely the Hustle before the match. I can still hear Bernard Gent in my head to this day. "Ladies and gentlemen, boys and girls, welcome to Ayresome Park"
The Hustle was definitely played every week but whether it was before, after or at half time I can't remember.

What I do remember is the pipes going:

Doo doo doo
dudoo dudoo
doo doo.
I also remember that tune, it was also used on an ICI petrol add,if my memory serves me well.
As a few posters have said, it was neither of the Van McCoy tunes - it was the
Duh duh der duh duh duh derrr one.
That sad tune must have been intended to have a calming effect after a bad result. Maybe the police chose it.
