The pick has to be the Xfm Remix/Wall Of Sound Xmas Special, which has probably assembled one of the finest line-ups London has ever seen, to, er, spell out the alphabet with - an artist for each letter playing a party choon. So that's 26 DJs with Arthur Baker kicking things off and Zoot Woman finishing, all in aid of homeless charity Shelter. In between there's Blak Twang, Coldcut, Gilles Peterson, Erol Alkan and Lottie. We'll leave you to work out who's doing X and Q.
