Drifting and Dreaming of You by Valerie Carter

Valerie Carter (1953-2017) sings Drifting and Dreaming of You from the 1975 film, White Line Fever.
According to Wikipedia, Steve Winwood's song "Valerie" was reportedly about her, as was Jackson Browne's song "That Girl Could Sing."
I've never been a big fan of country music, but have always loved this song since first seeing White Line Fever on TV around 1976 or '77.
