Nick Mason has refused to rule out a full Pink Floyd reunion, saying the band were just waiting for the right cause.

The Birmingham-born drummer will be at St Paul's Gallery in the Jewellery Quarter on Friday, signing copies of a fine art print of Pink Floyd's Relics album sleeve.

Speaking exclusively to The Birmingham Post, Mason said that relations between the other members of the band – Richard Wright, Roger Waters and Dave Gilmour – were good at the moment.

"We're not at each other's throats," he said.

The band last played together at Live8 in July 2005, healing a bitter rift between Gilmour and Waters.

The guitarist and bass player were involved in a long legal fight over ownership of the Pink Floyd name after Waters left the band in 1987.

Mason was always considered the bridge between the two camps, having maintained friendship with both parties.

He told The Post: "I'm pretty sure we'll play together again, we're just waiting for the right cause to come up. The main reason for doing it would be to benefit charity.

"Actually, it nearly happened last year at a tribute concert for Syd Barrett.  Everyone was up for it but Roger had a gig at Earl's Court on the same night. It was only logistics that stopped us.

"I think we've reached an interesting stage in our lives now. We've proved we can be successful as a band, successful as a band without Roger and successful in our own right.

"There's nothing else to prove.".

Nick Mason will be at St Paul's Gallery, 94 Northwood Street, Birmingham, Friday from 5.30pm to 9.30pm.
