Yes, mine Simon. Many years ago, late 70's or even possibly very early 80's I think I was at Sheffield's Kay Gee Bee all nighter. When I used to go to the Kay Gee Bee I always used to sit with Adrian Gyte who jointly ran the Strads record bar with Steve Croft. One night he was there with a box with some rather odd things in it. Several of these were on coloured vinyl & looked quite strange to say the least. A Pointer Sisters - Send Him Back on yellow vinyl, A Dutch Robinson - Can't get along Without You on gold vinyl (& also black vinyl), possibly a James Lewis - Manifesto on coloured vinyl & a Professionals on gold vinyl. This is fact as I bought the Pointer Sisters & a black vinyl Dutch Robinson & an old friend of mine from Sheffield bought the Professionals.
The Pointer Sisters has long gone but there is a thread on here that mentions it & here's a pic of somebody else's copy. Now has my mate still got the Professionals? Sadly not as he gave it to his brother who gave it to an old girlfriend.
Have also been told about someone with a similar box of coloured label things at Wigan Casino one night but wasn't there so can't confirm this.
Now don't get me wrong, I'm not suggesting it was a bootleg but I'm not saying it wasn't either.
