The Evening Standard saw Alan Yentob at the BAFTAs after-party thrown by fellow film mogul Harvey Weinstein. "In the corner we spotted Alan Yentob, catching up with friends and looking dapper. Alas, he chose not to wear his much-loved check pyjamas trousers."
Here's a picture of the waiters engaged for the event, at the Rosewood Hotel in Holborn. Perhaps Alan now has to ring ahead, to check what the staff might be wearing.
