Why They Split: Band relations hit a real low on the band's 1980/81 Wall tour, but after Roger Waters left in the early 1980s, the remaining trio of David Gilmour, Richard Wright and Nick Mason got along quite well and turned into a functioning unit. They also packed stadiums all around the world, but after 1994's massive Division Bell tour David Gilmour had enough. They quietly went on an indefinite hiatus when the tour wrapped after a long run of shows at London's Earls Court in October of 1994.
Last Performance: The classic line-up of Gilmour/Wright/Mason/Waters did a four-song set at Live 8 in the summer of 2005. Three years later Richard Wright died of cancer – forever ruling out a complete reunion. In May of 2011 David Gilmour performed "Comfortably Numb" with Roger Waters at London's 02 Arena, and Mason (playing tambourine) came out with Gilmour for "Outside The Wall."
Odds Of A Reunion: Another charity event may bring the surviving trio again for a handful of songs, but David Gilmour has been extremely clear that he has absolutely no interest in a Pink Floyd tour – with or without Roger Waters. He has more than enough money to stick by that pledge, so we're gonna put the odds of an actual reunion tour at 15%.
