"Dream Baby (How Long Must I Dream)" is a song written by Cindy Walker which was first recorded and released by Roy Orbison originally as a non-album single in 1962. It was a big international hit for Orbison, where it reached number 2 in both the Australian and the U.K. singles charts and number 4 in the U.S. Billboard. It was also a top ten hit in Canada and Norway. Five months later, "Dream Baby" was included on Orbison's Greatest Hits compilation LP.
The Beatles performed the song in front of a live studio audience on 7 March 1962 for the BBC radio programme Teenager's Turn, which was broadcast the following day. This was the Beatles' first ever BBC radio session. It has never been officially issued.
