What has that prep been like?
Well, in the show I play a piano player so I just had to practice the piano.
I don’t have to do any dancing.
But we recorded the music a few weeks ago and it’s kind of old hat for me.
I did a series calledSmasha few years back.
So, yeah, it’s pretty simple.
Does it feel likeSmashall over again in some ways?
A little bit, yeah, sure.
But what’s kind of fun about this one is we’re doing this dream sequence.
John Barrowmanwas geeking outabout you being on set.
Yeah, because he watchedSmash.
He plays it super cool backstage so you wouldn’t know he was geeking out.
Well, sadly for me I only really get to work with Carlos, John, and Grant.
So Winn and Ciscodon’tget to interact.
Winn doesn’t even come with them!
How do you think he’ll feel when he hears what they went through?
Oh, he’s pissed I’m sure.
But I’m sure it’ll happen.
This is kind of a fun alternative to that.
How do you think Music Meister compares to some of the other villains we’ve seen on the show?
Well, he’s quite different 100 percent.
What’s been the hardest part about doing a musical crossover?
We’re just having fun and I just act like an idiot and play the piano.
Yeah, it’s been fun.
