Born in Jackson, Mississippi, in 1946, Dorothy Moore started her professional career in 1965.
Misty Blue was released in 1976.
She still performs today, and has won 4 Grammy awards.
This is Dorothy Moore singing "Misty Blue" in a video made for television broadcasts.
Like many videos on the internet, all versions I find of this ends abruptly before the song ends, so I include an audio-only video below it.
