"Hello, Goodbye" is a song by the Beatles. Though the songwriting credit is Lennon–McCartney, it was written solely by Paul McCartney.
The song was released as a single in November 1967, and topped the charts in the United States, the United Kingdom, France and Norway. The song also was a number two hit in both Austria and Switzerland. In the United States, it becoming the band's 15th #1 there and was also included on the Magical Mystery Tour album released three days later, In Britain, however where it spent seven weeks at number one, and was the Christmas number one for 1967, the song was not made available in the UK on an album (or in stereo) until the release of the 1973 compilation album 1967–1970.
Alistair Taylor, who worked for the Beatles' manager, Brian Epstein, had asked McCartney how he wrote his songs, and McCartney took him into his dining room to give him a demonstration on his harmonium. He asked Taylor to shout the opposite of whatever he sang as he played the instrument—black and white, yes and no, stop and go, hello and goodbye. Taylor later said, "I wonder whether Paul really made up that song as he went along or whether it was running through his head already."
Three promotional films were made for the song; directed by McCartney, they were filmed on 10 November 1967 at the Saville Theatre in London. The films were not aired by the BBC due to the Musicians Union's strict rules on miming; with no such restriction in the US, one of the films was screened on The Ed Sullivan Show on 26 November.
