'For the finale it was dumped on the ground, covered in fake blood and stamped on.

'People got caught up in it for a start but the mood in the place started to change.'

According to The Sun, one audience member said: 'How could anyone think it’s acceptable?'

Posting about his act on social media before the event, Irvine, 22, bragged: Fake blood is my thing.'

He added: 'Did anyone ever find that missing child years ago? Come find out, be there.'

A spokesman for Madeleine's parents Kate and Gerry - who should have celebrated their daughter's 13th birthday last month - slammed the performance.

Clarence Mitchell said: 'The offensiveness of this act speaks for itself.'

But Irvine, who also works as a waiter in Aberdeen, said: 'It's a drag show. It's supposed to cause offence.

'I've heard one negative comment but so much praise. I entertained on the night.'

Asked directly about the feelings of the McCanns, he said: 'I feel for the family.'

He added of the performance: 'It was supposed to be extreme and edgy.'
