Lily Allen's performance of "The Fear" on Jimmy Kimmel on Friday was a lot more muscular than her performances on other late night shows recently. Her band sounds louder than the backing band for a pop singer should be, but it's better than the awfully quiet version of "The Fear" she did on the Today Show . Allen also played "Not Fair" as the episode's closing credits music, and that too was like an arena band playing a pop song.
