The Fab Four- lovable moptops from Los Angeles, have upped the stakes in the contest to be the world's best Beatles Tribute Band. They're young, talented, have a left-handed bass player and played at Eric Idle's birthday party. These two albums of frighteningly accurate parodies meld the Beatles' instrumentation and the production values of Sir George Martin with a selection of traditional Christmas melodies. Most are based on single tracks with some merging ideas from two. The playing and arrangements are faultless and several tracks have a magical moment when the sudden realisation of which song you're actually hearing hits you and it's hard not to laugh out loud. It would spoil the fun to reveal which tracks are based on which songs but my personal favourites are 'Santa Claus is Coming to Town and Good King Wenceslas'. If you're a Beatles fan or know one, buy it before next Christmas.
