The theme song
I wonder if gloria estefan sings it.
shareIt is her singing it
shareIn the original series, I believe it was Bonnie Franklin singing it (she came from musical theater) with Mackenzie Phillips in the background (she is a singer, as well). Not sure if Valerie Bertinelli was part of the background, hard to tell.
