Of course he bloody would.
The 'If You See Kay' singer 'revealed' this 'exclusive' to Digital Spy, saying he would in fact sing on the show "If [he] was invited [as] it's a music show at the end of the day".
He must be thinking of a very long day. Sometime mid-to-late June, perhaps.
"Would I be judging on the show?" he mused, "Probably not. But would I go on the show to promote a song? I'd be foolish not to. There's millions of people watching — same as with any show."
The singer also had a piece of advice for other bands out there so if that's you LISTEN UP.
"And by the way, this is for every band out there, if you get to go in a show, go on the show. Don't be too cool for school because it doesn't matter. Millions of people watch all of these shows and it's a really good platform."
