When i was about 13 i heard this song by Earth Wind & Fire, called "Let's Groove tonight"
I thouroughly enjoyed it and kept remembering the part: Mister Scrooge! get you to move.
I found out 4 years later (17 years old now and desperately searching for that really cool song) that the actual words were: Let this groove! get you to move
