"Play that phucking music white boy"
(play that funky music right boy)
Two mondegreens in one post.
The correct lyric is "play that funky music white boy".
And to clarify, it's only after that that he says "Play that funky music right." In other words:
"Play that funky music white boy
Play that funky music right
Play that funky music white boy
Lay down that boogie and play that funky music till you die"
I also find it humorous that the "lyrics site" I found these at (just to be absolutely certain I got it right),
credits the song to James Brown
