Osborne was given the job in February, months after the original frontman was forced to quit three songs into a gig in Switzerland, leaving his bandmates fearing that their careers were over.

But with McCafferty's blessing, Nazareth powered on and hired their second-ever vocalist, who was previously a club singer - and once regularly dressed as a vampire Elvis character in a previous band.

He made his first appearance with the Scots veterans last month in Inverness. Just before he went on his predecessor left a message on his phone.
