Whoa! Is that Denny Laine in that picture with George?

Yes he is it.

March 15 1986

In the UK at the National Exhibition Centre, in Birmingham, George joins in the all-star finale at the Heartbeat '86 marathon charity rock concert. The event is the brainchild of the Electric Light Orchestra drummer Bev Bevan and the first in a series of different ideas to raise �1 million for the Birmingham Children's Hospital. Performing alongside former Led Zeppelin vocalist Robert Plant and former member of Wings, Denny Laine, George shares lead vocal on the tracks 'Money' and 'Johnny B. Goode'. The concert, which attracts a capacity 11,500 audience who paid gate receipts of �200,000, is videotaped by BBC Television and is transmitted on BBC1 on Saturday August 2.

"At his Hurtwood Edge home in Surrey, Eric Clapton throws a party for 200 guests to celebrate his marriage to George's first wife, the former Patti Boyd. (The couple married in Tucson, Arizona, on March 27.) At the end of the evening, Paul, George and Ringo, as well as the other celebrities present, including Mick Jagger, Denny Laine, Ginger Baker and Lonnie Donegan, join Eric for an impromptu concert on a stage set up in a large marquee tent in his grounds. They run through various old rock'n'roll hits and even some Beatles' covers. Friends and family take souvenir pictures of the event, although none have appeared in print."
