The Who frontman Roger Daltrey has thrilled die hard fans by making a surprise appearance at this year's (06) annual The Who Convention. The SUBSTITUTE hitmaker visited London's Bush Hall on Saturday (01APR06) along with Pete Townshend's brother SIMON and sang songs including BEHIND BLUE EYES. Organiser/fan RON DOVEY says, "It was absolutely superb. People can't believe he came to our convention and sang for us." The event is organised by fans and benefits Daltrey's favoured charity the Teenage Cancer Trust.
