Aerosmith frontman Steve Tyler has rubbished rumours he has throat cancer, after his sudden withdrawal from a string of tour dates left fans panicking. The rocker, whose gruelling Rockin' The Joint tour started last autumn (05), has been ordered to rest by his doctor after suffering from strained vocal chords and influenza. Boston resident Tyler was spotted ordering some healthy provisions at popular store Whole Foods Market in Hingham, Massachusetts, and an onlooker claims he could barely speak. He says, "He sounded like he had laryngitis and he had someone doing the ordering for him." A spokesperson for Tyler insists cancer claims are "absolutely untrue".
