It was mashup of all mashups on Jimmy Kimmel Live between CeeLo Green and KC and the Sunshine Band.
The two joined the stage as part of Kimmel’s “Mashup Mondays” where they performed a combination of KC and the Sunshine Band’s “Get Down Tonight” and CeeLo Green’s “Bright Lights Bigger City.”
CeeLo had such a great time he even tweeted out, “I had a blast last night performing on @JimmyKimmelLive w/ @kcandsunshineb for #MashUpMonday!! Watch us rock!!”
Check out their mashup above.
