"Mr. Brown" is a song by Jamaican group The Wailers. Recorded in 1970 at Randy's recording studio in Kingston, it was produced by Lee Perry and written by regular Upsetter musician Glen Adams. It was originally released as a single in Jamaica and has appeared on various compilations such as Songs Of Freedom.
Because it's based on a ghost rumor, the song has lyrics and instrumentals based on a spooky style. The instrumental is called "Dracula". The song has been featured on a few Halloween albums, and has a remix with DJ Spooky.
The song's music sampled Jackie Mittoo's "Peenie Wallie."
