If he sings this he'll make it to the final, no question

Weird thing on a list of videos they showed by this video, I saw one with Marcus on it, maybe it's a sign

What's the theme?

Glee did a nice mash up of that and I Can't Go For That Perfect cutesy number for Marcus

i'm not sure if there's a theme but with what Marcus has been doing that song would suit him down to the ground and that song is really popular right now

I can't remember. Has there been a theme at this stage in the competition before or is it down to the contestant/production?

usually one song is chosen by the mentor and the other is a song the contestant think's will take them into the final

Oh ok, Hmmm. If he sticks to the cutesy formula he'll get through to the finals no problem. The public seem to love the cheese.
