17 Again: The Musical

This is a random one folks.

On the Zachary & Weiner website there are three songs from the demo recording of 17 Again: The Musical and I'm wondering if anyone knows who's featured on each track? From what I understand, Darren Criss plays Mike, the role Zac Efron originated in the film, but apart from that I'm clueless. You can listen to the songs here and see if you can pick anyone out.

Any and all help is appreciated!

Seriously?

This movie didn't even develop a cult following, and what popularity it did have was from teenybopping Zac Efron fans. I'm all for artfully adapting great films for the stage, but we ought to draw the line somewhere!

At least this one will have an original score, I guess...
