As Kev H has already said - a Rob Marriot spin first.
As for "many of the favourites that are played at the "oldies" venues, were originally spun by him, years ago....." I would stick my neck out to say just as many top tunes came from Rob Marriot imo.
Butch has broke some fantastic tunes over the years without a doubt. But is he still doing it?
I haven't seen him DJ a lot recently so I really can't comment.
But going on the times I have heard him recently, and I don't mean any disrespect when I say this, I'd say no he isn't.
Would be interested to hear from people who do see him DJ regularly though.
