Fifty years ago last (Sunday) night, February 9th, 1964, 73-million people watched The Beatles make their debut performance on The Ed Sullivan Show. Last (Sunday) night, 50 years to the day and time, CBS aired a two-and-a-half-hour special celebrating that event and the impact it had on America.

The Night That Changed America: A Grammy Salute to The Beatles featured archival footage interwoven with performances taped last month in Los Angeles by Joe Walsh, Jeff Lynne, Dave Grohl, John Mayer, Katy Perry, John Legend, Alicia Keys, Keith Urban and many others, with a backing band that included Peter Frampton and Toto's Steve Lukather.

Paul McCartney and Ringo Starr -- along with Yoko Ono and Olivia Harrison -- were in the audience and then did sets of their own as well as together on "With a Little Help From My Friends" and "Hey Jude."

Perhaps the most interesting parts were the interview clips Paul and Ringo did last week with David Letterman in the Ed Sullivan Theater in Manhattan, which is where the Sullivan show was staged. They reminisced about being in the theater that night, with Paul saying it's "like going back to your old schoo," the impact their performance had, how they came up with the name of the group and its meaning, and Paul being reminded that 73-million people were watching as he was about to perform "Yesterday."

Note to Paul and the writers and producers of last night's show -- The Beatles did not perform "Yesterday" on the Sullivan Show until their fourth appearance on September 12th, 1965. And one other thing -- George Harrison wrote "Here Comes the Sun" at Eric Clapton's home outside London, which is called Hurtwood Edge, not Huntwood.
