2005–2014: Reunion, deaths, and final album
Live 8 reunion
On 2 July 2005, Waters, Gilmour, Mason and Wright performed together as Pink Floyd for the first time in more than 24 years, at the Live 8 concert in London's Hyde Park. Organiser Bob Geldof arranged the reunion, having called Mason earlier in the year to explore the possibility of their reuniting for the event. Geldof asked Gilmour, who turned down the offer, and then asked Mason to intercede on his behalf. Mason declined, but contacted Waters who was immediately enthusiastic. Waters then called Geldof to discuss the event, scheduled to take place in one month. About two weeks later Waters called Gilmour, their first conversation in two years, and the next day the latter agreed. Gilmour then contacted Wright who immediately agreed. In their statement to the press, they stressed the unimportance of the band's problems in the context of the Live 8 event.
They planned their setlist at the Connaught Hotel in London, followed by three days of rehearsals at Black Island Studios. The sessions were problematic, with minor disagreements over the style and pace of the songs they were practising; the running order decided on the eve of the event. At the beginning of their performance of "Wish You Were Here", Waters told the audience: "[It is] quite emotional, standing up here with these three guys after all these years, standing to be counted with the rest of you ... we're doing this for everyone who's not here, and particularly of course for Syd." At the end, Gilmour thanked the audience and started to walk off the stage. Waters then called him back, and the band shared a group hug. Images of that hug were a favourite among Sunday newspapers after Live 8. Waters commented on their almost twenty years of animosity: "I don't think any of us came out of the years from 1985 with any credit ... It was a bad, negative time, and I regret my part in that negativity."
