Paul McCartney threw off his divorce woes in a celebration of old time rock 'n roll at the 'Last Play at Shea'.

The former Beatle took on old-time rocker Billy Joel in a battle of the bands at the final concert at Shea Stadium in Queens, New York.

The concert nearly ended as the first show in 1965 began, with Sir Paul, 66, singing 'Let it Be' over a deafening crowd.

Despite a combined age of 125, Sir Paul looks a good 10 years younger since his harrowing divorce battle

At one point, clearly enjoying the celebration, Sir Paul gave host Billy Joel, 59, a good old-fashioned smacker on the cheek.

Together, Sir Paul and Billy Joel have a combined age of 125. Yet Macca still looks 10 years younger since his painful divorce battle.

Earlier in the night, Sir Paul pleased the 63,000 screaming fans with a singalong of Piano Man.

Other stars at the concert included Aerosmith lead singer Steven Tyler, who looked particularly well preserved, and Tony Bennett.

With a total combined age of 267, the old time rockers saw off the Shea stadium in style.
