Dennis Rodman put in WORK on the streets of Vegas Monday night … teaming up with a bucket drummer outside Planet Hollywood … and the people loved it!
We're told it all went down around 10 PM … when Rodman was walking around the strip and saw the dude murdering the bucket drums.
Rodman grabbed the mic and busted out James Brown's "Get On Up" … and it wasn't bad.
Shout-out to the guy in the background trying to put down one of those giant slushy drinks from Fat Tuesday. Enjoy the hangover, pal.
