The theatre has had a leaky roof since it was damaged in the bombing of London during World War II!
Macca will be playing for 450 people at The Boiler House at Battersea Power Station and Spacey, the theatre's artistic director, says:
"We are thrilled Paul McCartney will lend his extraordinary talents on the evening alongside brilliant artists who've generously donated their artworks for auction. It's set to be quite a night."
Money raised will go the the theatre's trust as well as McCartney's Meat Free Monday campaign.
Good for him!
