It was "Good Day Sunshine" for the international space station crew Sunday morning.
NASA astronaut Bill McArthur and Russian cosmonaut Valery Tokarev were treated to a live wake-up call of the Beatles classic in a first-ever concert linkup to the space station.
On Earth, former Beatle Sir Paul McCartney performed the hit and another song, "English Tea," for the space duo on Saturday night in Anaheim, Calif., before a cheering crowd as part of his 11-week "US" tour.
The performance was beamed from the West Coast to the space station crew 220 miles above Earth and broadcast on NASA television, which showed live feeds from space.
McArthur and Tokarev bobbed up and down and sipped from squeeze pouches through the show, getting a rousing cheer from the audience.
