Ex-Wings guitarist Henry McCullough suffered a devastating heart attack in 2012 and then endured a lengthy period of partial recovery.

As these songs by the Beatles, the Rolling Stones and others show: Sometimes, having special guests provides just enough competition to make the main act work a little harder.

When Pink Floyd’s ‘The Wall’ arrived on Nov. 30, 1979, it included a deep cut that perfectly summed up the theme. Too bad he kept going.

Pink Floyd’s ‘Wish You Were Here’ arrived on Sept. 12, 1975 after a lengthy, very difficult period of creative inertia, Nick Mason says.

Even in an era when envelopes were often pushed, Pink Floyd’s “Alan’s Psychedelic Breakfast” proved to be utterly outrageous.

Pink Floyd recorded its 1967 debut just one studio over from the Beatles at Abbey Road. But Roger Waters says that’s where the similarities end.

Pink Floyd didn’t finally begin its journey toward the platinum-selling group we all know until years after its founding. Nick Mason can tell you when.

Nick Mason is the only member of Pink Floyd to have appeared on each of the group’s studio project – but he didn’t play drums on every song.

David Gilmour might never have returned to Pink Floyd but for a magical moment with Richard Wright and the sweeping finale to 1971’s ‘Meddle.’

Combine David Gilmour’s “Out of the Blue” – released March 27, 1984 – with the best of The Final Cut, and you’d get the next great Pink Floyd album.
