Dateline: Thursday June 24, 1976, Benedict Canyon, California. Paul McCartney is holding a lavish party in a mansion owned by Hollywood silent movie star Harold Lloyd to celebrate the American conclusion of the Wings world tour. It’s been a wild success: the biggest grossing tour of the year by any rock group to date. The night before, Wings have been rapturously received at the Los Angeles Forum. Recordings from that concert will form the bulk of the triple album Wings Over America.This party is costing someone $75,000. The guest list includes Paul’s new mate Rod Stewart, David Cassidy, actors Jack Nicholson and Tony Curtis, and all of the Beach Boys apart from McCartney’s hero Brian Wilson – he’s going quietly nuts in Bel Air.The guests’ invitation reads ‘Wear all-white’, and they’ll soon find out why when a troupe of Hawaiian street artists with aerosol guns decorate the party-goers with red and blue paint. Just before the end, McCartney prays silence. He delivers a speech. “After The Beatles [cheers], you’d have thought it would have been pretty much impossible for me to follow that and to get anything else going [greater cheers]. At least, I thought that… [murmurs of “no, no”]. This tour has convinced me, I mean us, that we are a group, and I think it’s convinced audiences [louder cheering]. This isn’t just a one-time trip [shrieks and whooping]… this is going to be a working band!” While the snuffed-up celebrities surge forward to shake his hand Macca raises thumbs aloft, then shouts out: “We’ll be back!”
