In the VT before his act, Marc explained: 'When Tessa was pregnant she was diagnosed with breast cancer but we got through it. It was magic and that was inspiration for my act.
'I'm doing this for my girls, they are everything to me.'
For his act, he made the judges pick words at random from cards containing inspirational quotes, books featuring over 1,000 incredible human beings and David Walliam's one book,Mr Stink.

After Simon Cowell revealed the last word in the quote he had picked had been 'heart', Marc drew out a picture drawn by his daughter Isabella, which was of a heart.
Alesha then revealed the inspirational person she had picked at random had been Ghandi, at which point Marc showed a painting he had put on the stage of the inspirational leader, alongside a clip of his daughter saying 'Ghandi'.
He then quickly rearranged the squares on his painting to reveal a picture of John Lennon, as Amanda Holden revealed that was who she had been thinking of.

Speaking afterwards, Amanda gushed: 'Oh gosh, I don't know how you do it. Even though the magic is extraordinary it's the emotional pull of the story behind it.
'It didn't have the same pull as your first audition, but still very well put together.
Simon, notoriously hard to please, was also impressed, revealing, 'everywhere I've gone people are talking about you. I don't want to call it magic because that's too small for what you do.
David added, 'you make magic beautiful', as Alesha chocked back tears to admit: 'I was almost in a trance watching you. You did a brilliant job.'

During his audition, Marc had left troubled presenter, Ant McPartlin, fighting back tears with his magical routine and secured a place into the semi-finals after the presenter hit the golden buzzer.
Following his success, Marc opened up about his wife's breast cancer battle while she was pregnant with their longed for baby after years of failed IVF.
During his audition, the talented act used his family's past heartache as an example of 'real magic' after Tessa managed to beat the deadly disease and welcome their precious daughter Isabella two years ago.
