From the wiki: “‘Babe I’m Gonna Leave You’ was written by Anne Bredon née Johannsen in the late 1950s. Bredon appeared on the live Folk music radio show, The Midnight Special, on Pacifica radio’s KPFA singing ‘Babe I’m Gonna Leave You’. A fellow Folk singer guesting on the program, Janet Smith, took up the song and developed it further, playing it live at hootenanny events at Oberlin College, one performance of which was attended by Joan Baez. Baez requested of Smith to send her a recording of her songs, including ‘Babe, I’m Gonna Leave You’, which Baez subsequently began performing herself.
“Vanguard Records, Baez’s label, later sent Smith a letter asking if she had written ‘Babe’. In the meantime, Baez had recorded the song and included it on her In Concert album. Initial pressings listed no writer’s credit for ‘Babe’. The 1964 recording by the Surrey, England, band The Plebs credits ‘Trad arr. Dennis’ but, later the same year, the Joan Baez Songbook rightfully lists Anne Bredon as the author as does the 1965 recording of the song by The Association. (It was the group’s first single release, but had no chart impact.)
