She said the song was to go on an album with Buckingham but the studios (Clive Davis) at the time rejected the song saying it was not what people wanted to listen to. She often dedicates the song to her father for standing with her during her troubled time with Buckingham and the music world in general. I believe she made a pact with her father at the time she would give the music scene 1 more year to see if she had a future in it. Hence her pal a studio engineer introduced Buckingham to Fleetwood (who needed a guitarist for the band at the time, to go on tour) but only as a package deal with Stevie Nicks. They accepted the deal - she offered the song to Fleetwood, they liked it, recorded it, it has become a widely covered hit song proving once again corporate people who often guide our music tastes don’t always get it right. Bully for Nicks sticking to her instincts.
