The Pink Floyd drummer has a self-confessed ''disgusting'' indulgence in collecting motors and he likes to meet up with the AC/DC singer to chat about their similar vehicle obsessions.
Speaking at the Classic Rock Roll of Honour in London on Tuesday night (13.11.12), he told BANG Showbiz: ''I'm supposed to be meeting up with Brian to talk cars next week. It's great.
''Collecting classic cars has always tacked along with the music. The music is something I do which has allowed me to indulge to a disgusting degree in racing cars.''
The 68-year-old stickman has made no secret of his classic car collection - which includes a £23 million Ferrari 250 GTO - but the musician admits he had originally intended to keep the location of his haul of expensive motors a secret until they were the subject of a feature on Chris Evans' radio show.
He added: ''They were meant to be kept in a secret location until Chris Evans broadcast it on the radio. They are in the West Country, somewhere in Cirencester.''
