I believe that was Timmy Mallet on Piccadilly Radio. Yes that rubber hammer wielding idiot!!All this talk about breaking records reminds me, FOC that i am, of that music show on the radio many, many years ago when people wrote in with requests for songs they hated and after it had been played they got to listen to the sound of the record being smashed to pieces.
Younger folk, look up "records that could be broken in bits."
(P.S. it wasn't on the radio, it was on the wireless.)
