This is a rare version of the song Todd Rundgren wrote about Laura Nyro, who he cites as a major influence (this is the one that was actually released). She also had a long-term affair with Jackson Browne, who wrote “That Girl Could Sing” about her:
Baby Let’s Swing
Susie, thank you. I love Laura Nero. Rundgren leaves me wanting.
Thank you for all the music.
Damn, I never pursued her, because I thought she was gay!
She converted later, after her divorce.
