Lily Allen posted her new single on Twitter with the following warning: "If you thought the Bare and Hare was annoying, you won't want to watch this." That's a reference to her Christmas ad Keane cover, and she is … not totally wrong? Especially in that "Air Balloon" sounds like Lily Allen improving someone else's song more than it does a Lily original. It is cheerful, though. Would you like something cheerful this Monday morning?
