Fans are buzzing as to whether Paul McCartney and Ringo Starr will join forces on Sunday night (January 26th) for the live Grammy telecast. Both former-Beatles are billed to perform on the show separately, and the next night (January 27th) join forces for the taping of CBS' The Night That Changed America: A Grammy Salute To The Beatles, which will air on February 9th -- 50 years to the day of the Beatles' first Ed Sullivan Show appearance. In addition to McCartney and Ringo's performances, John Lennon and George Harrison's respective widows, Yoko Ono and Olivia Harrison, will appear as Grammy presenters. On behalf of the "Fab Four," McCartney, Ringo, Yoko, and Olivia will appear together and accept the 2014 Recording Academy Lifetime Achievement Award.

McCartney is up for four Grammys for several different projects -- including Best Rock Song for his recent collaboration with Nirvana's Dave Grohl, Krist Novoselic, and Pat Smear on the Sound City track "Cut Me Some Slack." He's also nominated for a vintage recording in the Best Boxed Or Special Limited Edition Package category for his massive 1976 Wings Over America - Deluxe Edition. "Macca" also scooped up noms for Best Music Film and Best Surround Sound Album for his Live Kisses DVD from his intimate standards performance at L.A.'s Capitol Studios.
