Craig sang his own track, Come Waste My Time, in Saturday night’s live final as millions watched the 23-year-old claim victory and secure a professional record deal.
His heartfelt performance hit the right note with viewers as thousands have downloaded the single – putting the former Greggs worker in atop the iTunes chart ahead of Nathan Evans’ Wellerman (Sea Shanty) and All You Ever Wanted by Rag'n'Bone Man.

“I just want to say thank you very much because without your support I wouldn’t be here. What you’ve done for me in the past month and a bit has been absolutely incredible.”
