Pink Floyd's Roger Waters has said he "won't be unhappy" if the band's performance at Live 8 in 2005 proved to be their last.
"It was an extraordinarily moving experience for me and if that's the way we draw a line under Pink Floyd, so be it," he told BBC News.
Waters, 66, will tour the band's classic album The Wall later this year.
He said Pink Floyd had been asked to reform for a show in New York but that bandmate David Gilmour had refused.

Waters returns to The Wall
"I think Live 8 was probably it," Waters told the BBC's Rebecca Jones.
"And Live 8 was so beautiful, and Rick obviously was still with us then."
The band's keyboardist, Richard Wright, died in September 2008.
"If that's the way we draw a line under Pink Floyd, so be it," Waters said. "I won't be unhappy about that."
He said he had been asked by Hank Steinbrenner, co-owner of New York's Yankees Stadium, to reform the band to perform 1979 double concept album The Wall.
"I said, 'well, I don't think David wants to do anything again, and certainly not this'.
"He said, 'well, will you ask him?' So I did, and he said no.
"Which I knew he would and there's no reason why he wouldn't say no."
Waters added: "However, if the others wanted to do something at some point, I'm always open to suggestions.
"So far, there haven't been any."
Waters will begin The Wall Live tour of North America in Toronto, Canada, on 15 September.
European dates will follow, beginning next May.
