There was this song called "mr. rich man" / "mr. richman" / "rich man" like that. The sound is typical early 80s dancehall. The lyrics go like (what I was able to comprehend):
"You running in your mouth
with your big long cigar"
"You running down town
in your big expensive suit"
"You running in a gamle room
with your pockets full of ..."
"And you know, you gonna win or lose"
"Hey mr.rich man, you trying to provoke I man"
Any help on ID would be gladly appreciated. I was listening to it way too much in 2010 and it brings super good memories, but I was not able to find it : ( Thank you in advance!
