“Good Day Sunshine” by The Beatles

"Good Day Sunshine" is Paul McCartney's slice of pure sunlight on Revolver, the Beatles' 1966 album, and he built it with the Lovin' Spoonful's "Daydream" in mind. Where the rest of the record goes stark and strange, this one throws the windows open: a stack of barrelhouse pianos, played by McCartney and George Martin, give it the bounce of an old music hall, all four Beatles pitch in on handclaps, and John Lennon and George Harrison sing behind McCartney's lead.

It's trickier than it lets on, sliding through key changes and odd shifts in meter before fading out on voices chanting the title. Some critics love its lightness and some think it dilutes the album. McCartney has played it regularly in concert, re-cut it for his 1984 film Give My Regards to Broad Street, and in November 2005 serenaded the astronauts aboard the International Space Station over a live link.
