The Vamps star James Mcvey has been banned from playing guitar on the band's Australian tour after undergoing wrist surgery.

The guitarist has been ordered to rest his arm for two months following the operation to treat a repetitive strain injury, but he has refused to miss the group's shows Down Under even though he can't play his instrument.

He has decided to take to the stage with his bandmates to sing backing vocals, while frontman Bradley Simpson tells News.com.au the guitarist will be their "vibe guy".

MCVey adds, "I got repetitive strain from playing guitar so had to have some surgery to fix it. I can't play guitar for two months."

The shows kick off in Sydney on Friday (23Jan15).
