Pink Floyd formed in London in 1965, and became a huge success story during the Seventies. However, Roger Waters left in 1985 although the rest of the group disbanded in 1995. Music fans were shocked when Waters joined David Gilmour, Nick Mason and Richard Wright on stage for their first performance together in 24 years in 2005 for Live8. The gig was watched by an estimated three billion people worldwide.

Writing in The Guardian back in 2006, Emma Brockes explained how the fallout that saw Waters walk away from the band was briefly forgotten for Live8.

She wrote: “[Gilmour]s] fall-out with Pink Floyd’s bassist, Roger Waters, was a very English affair that involved almost two decades in which the men did not speak to each other after Waters walked out of the band in 1983.”

Waters then claimed that the band had dissolved without him, but it continued to release hit songs.

Recalling her interview with Gilmour, Ms Brockes wrote: “Things came to a head over a row about songwriting credits, but the real cause of the fall-out, says Gilmour, was a straightforward personality clash.”

She continued: “They wound each other up just by being the people they were — Waters’ ‘bossy’ assertiveness versus Gilmour’s resentful unassertiveness, his ‘allowing’ himself to be ‘messed up’.”

As a result, Gilmour rejected Bob Geldof’s suggestion that they reunite to perform for Live8.

He told The Guardian: “Not because I didn’t think it was a very good cause.

“But I just felt it would get along fine without us.”

However, Geldof worked hard to persuade him.

Once Gilmour had been talked around, he and Waters met in a London hotel room to try to smooth things over.

Gilmour recalled: “And it…it was pretty weird, obviously, going into that same room.”

He added that it only took two minutes for the dynamic to revert to how it was when they were in the same band.

Gilmour explained that as a result the first meeting was “pretty stilted and cagey”.

They had three days of rehearsals afterwards together, but it was a struggle for the two feuding men to work through their personality clash.

Gilmour explained: “It was a struggle for me sometimes to assert myself, because I’m fairly laid back and reticent.

“And Roger is very assertive and there were times when he wanted something to happen, wanted to make a decision, and it wasn’t the way I wanted it to be; so we got into a few minor arguments.”

However, the gig was a huge success, supposedly because the band realised the gig was significantly more important than their own conflicts.

The two performed together again for charity in 2010 for the Hoping Foundation, but in August 2015, Gilmour explained that the band was well and truly “done” following the death of bandmate Wright.
