US President Barack Obama and his family were bouncing in their seats at a White House tribute concert for former Beatle Sir Paul McCartney.
The setting was the ornate East Room, with an all-star line-up cranking out some of Sir Paul's greatest hits.
Stevie Wonder had the Obamas clapping to We Can Work It Out, the Jonas Brothers did Baby You Can Drive My Car and British star Corinne Bailey Rae slowed things down with Blackbird.
Fellow Brit Elvis Costello crooned Penny Lane, and called it a "thing of wonder and beauty", noting that his mother grew up not far away from the now-famous street in Liverpool.
For all the awards the former Beatle has collected over the years, he said performing before the Obamas in the East Room was still a pinch-me moment. "For an English kid growing up in Liverpool, the White House - that's pretty special," he said.
Of his host Mr Obama, Sir Paul added: "He's a great guy, so lay off him."
Comedian Jerry Seinfeld had lots of compliments for Sir Paul and one complaint - he couldn't quite figure some McCartney lyrics, such as, "She was just 17. You know what I mean."
Seinfeld said: "I'm not sure I do know what you mean, Sir Paul. I think I know what you mean. And I think there's a law enforcement agency in a couple of states that might want to ask you a few questions."
The Gershwin Prize, awarded by the Library of Congress, is named for the songwriting brothers George and Ira Gershwin. Previous recipients of the award are Wonder and Paul Simon.
McCartney played a private concert at the library on Tuesday, and said he'd grown up listening to music by the Gershwin brothers.
