He began by explaining how he had met the all-girl act Mahogany he had been mentoring on the show.

“Well, I met these girls on a tour that I did a little while ago, and they blew me away then, and then they walked into the audition room and blew me again,” Sebastian said, before realising what he had just said.

Until next time keep rockin’
