Beatles and go with old Phil Spector, or the drummer Jim Keltner. It was like a clique, and I just didn't want to join that clique." In 1971, Harrison invited his former bandmates to perform with him at the Concert for Bangladesh in August. Starr accepted, but Lennon and McCartney did not. McCartney refused because he was wary of Klein potentially taking the credit for having organised a Beatles reunion. Lennon agreed on the condition that Ono could also participate, but Harrison refused to invite Ono on the grounds that the concert was intended as an exclusive gathering of rock stars, not an avant-garde festival. Following the concert, much of the media attention was focused on the ostensible reunion of Starr and Harrison. In March 1973, Harrison joined Lennon, Starr and bassist Klaus Voormann for the recording of "I'm the Greatest", released on Starr's 1973 album Ringo. To Lennon's distaste, Harrison suggested that they form a group with this line-up. Amid the numerous financial and legal disputes plaguing the foursome, Lennon stated: "The only talk about Beatle reunions comes from people at the side of the Beatles who want to put us together and make millions and millions of dollars. And I'm not interested in that, or in playing with the old team again." However, he also said, "There's always a chance [of us reuniting]. As far as I can gather from talking to them all, nobody would mind doing some work together again. But if we did do something, I'm sure it wouldn't be permanent. We'd do it just for that moment." At Starr's request, McCartney also appears on Ringo, for the song "Six O'Clock". This made it the only album to include compositions and performances by all four ex-Beatles after the break-up, albeit on separate songs. Later in 1973, McCartney attempted to organise a reunion as a means of mitigating their collective legal burden. In February 1974, it was widely reported that the Beatles would soon reform, but although all four members were present in Los Angeles the next month, they chose not to meet. During the promotional run for his December album Dark Horse, Harrison remarked: "It's all a fantasy, putting the Beatles back together. If we ever do that, it's because everybody is broke. ... Having played with other musicians, I don't think the Beatles were that good ... I'd join a band with John Lennon
