Window in the Skies, which has been said to sound somewhat like Lucy in The Sky With Diamonds, is U2's new single. It is being released on January 1st, but in the meantime, there's a video featuring a cast of musical icons.
They include Elton in a shiny seventies outfit as well as the likes of Elvis Presley, Marvin Gaye, Frank Sinatra, Nat King Cole and Johnny Cash.
And everyone is on on lead vocals.
As for U2 themselves they are harder to spot.
