It actually goes back to Fritz. Javier posted it on youtube and it's attributed to Stevie.
Stevie Nicks sings an original song performed live by the members of the Fritz Rabyne Memorial Band at Fremont High School, Sunnyvale, 1968, with Brian Kane (guitar), Lindsey Buckingham (bass), Javier Pacheco (Hohner Clavinet), and Bob Aguirre (drums). Reunion pictures at the end were taken at the Concord Pavilion, Concord, CA (after a FM show) in June 2004.
