X-factor reject Wagner has become known for singing happy birthday to those willing to pay for the pleasure.
But this weekend he sent out a different sort of message – to Rangers Football Club.
He posted a video on his Facebook account saying it was from Paul McKay before launching into a rendition of Stand Free, Aberdeen FC’s anthem.
Not long into the performance though he begins singing a different song – one about Rangers.
He sings: “Rangers are guilty, guilty, of not paying their VAT.”
