While the Swedish Chef and Beaker of The Muppet Show have been singing Habanera, the aria from the opera Carmen, Bert and Ernie of Sesame Street have been trying something decidedly different ... like gangsta rap from M.O.P.'s "Ante Up": Hit play or go to Link [YouTube]
if you like muppets synced to different styles of music then here is the best one Ive seen. its the chuck e cheese animitronic band playing "love in this club" by usher. the synchronization is so good in this I really think it was an employee of chuck e cheese that actually programmed this song into their movements! very funny
