That's What Friends Are For
This SFGate writeup on the backround to De-Lovely has this surprising reference to a `pal` of Elvis -
Winkler then called Diana Krall, whom he'd cast in his 1999 film "At First Sight," to perform "Just One of Those Things." She told her husband-to- be, Elvis Costello, who sang "Let's Misbehave." Costello told his pal Robbie Williams, who crooned "It's De-Lovely." Sheryl Crowe vamped her way through "Begin the Beguine." Simply Red singer Mick Hucknall, unrecognizable as Nelson Eddy in a Canadian Mountie costume, crooned "I Love You," and young R&B singer Vivian Green gave a sultry "Love for Sale" reading.
