Does Paul McCartney still live at 7 Cavendish Avenue in London?

Answer 1

Not since The Beatles years. He visited there with Harrison and Starr in the Eighties, after they attended an awards show together.

WRONG. He's owned the property since 1966 and is still frequently in residence. He's not generally known to sell properties once he acquires them though that may have changed the last few years with the whole Heather Mills debacle. He had purchased property while married to her. He had a place in Beverly Hills, CA. He may have given it to Mills after the split or sold it off. The same would hold for anything he may have bought when he was with her.
