Nice mash-up.
Very very close to the original though.

OMG , Amazing!!
Excited that they're going into 90's boyband territory, I just wish they'd produce their vocals a little less musical theater style (even if it fits the premise of the show). It's like listening to background vocals with no exciting lead.
I love the mashup! sounded great.
