You remember him as the Lord of Darkness from the movie "Legend" with Tom Cruise, or as the creepy clown in that Steven King movie, or the creepy desk clerk in Home Alone 2, or as the creepy transvestite in what I consider one of the worst movies ever made.
Amidst all of that we was a singer. He released 3 albums: "Read My Lips" 1978 "Fearless" 1979 "Simplicity" 1981
This single is from "Simplicity" and is not his only attempt at reggae. There were two others. This was the lesser of the creepy.
