Seem to remember him doing the Anfield Rap under similar circumstances not so long ago as well...
Maybe he's feeling nostalgic? Or maybe he's been doing it for years and there's just more camera phones around these days?
Either way: Friday night, on the way to Wenbley for the Liverpool vs Barcelona friendly, this happened.
