Mary Travers (Peter, Paul and Mary.) From the Morecombe and Wise Show (1972 BBC) The laughter at the start was for a comedy skit which preceded the song.
The song was written by the late Ewan MacColl for his wife Peggy Seeger. When he wrote it in 1957 he sang it to Peggy over the telephone. A quote from Peggy: " Ewan never sang "The First Time Ever" himself after that phone call. It became my song"
