In part three of ET's Beatles exclusive, Paul McCartney, Ringo Starr, Yoko Ono and Olivia Harrison divulge more about the band and their eventual break-up.

And, before John Lennon's death in 1980, did the band ever consider reuniting?

"Not really. We talked about it a lot," Paul tells Mary Hart in our video. "And we always said that, if we did, it might not be great. Whereas, the Beatles' career had been great." He continues: "And even though the offers were huge, and there were sort of people going, 'I'll pay you this to do it,' we talked about it. And we sort of said, 'Nah, this is it. There is something not right about it.'"

For more with the Beatles, watch our video and tune in to ET tonight.

Paul and Ringo, along with Yoko (John's widow) and Olivia (George Harrison's widow), came together to celebrate two important events -- the release of a new digitally remastered complete Beatles catalogue of albums, as well as the debut of the Beatles edition of the popular video game, Rock Band.

The Beatles: Rock Band, as well as their digitally remastered catalogue, are available today.
