Check out what they had to say after the jump, andbe aware that there are spoilers.
DULE HILL: For me, it was writing.
I wrote all those songs out of my brain.
My name is Dule Hill, and I wrote every song.
It really was a hard thing to do.
No, you know Im lying.
But, it was worth it.
It was like one of those great body switching movies, and we really enjoyed it.
We learned a lot about ourselves, by switching bodies for a very short period.
Nobody said a word.
Nobody questioned it, for one second.
I cant begin to tell you how tired I imagined they were, watching them.
I just cant imagine the physical peak that these guys must be in.
He wrote the whole thing.
He composed it with Adam Cohen, and he directed it.
It was a gargantuan, Herculean task that he took on.
HILL: And we didnt have any extra time.
Thats what made it so daunting.
There were chases through the woods and there was this enormous fight with a hanging scene.
It was a big episode, even if you didnt put the musical numbers into it.
We had already shot 13 episodes.
We were at the end of our run.
Usually, everybodys running on fumes, anyway.
Across the board, everyone was really running on adrenaline.
We still dont know how we finished it.
Who in the cast surprised you the most, as far as their singing or dancing?
HILL: For me, I would vote for Tim Omundson.
He has an amazing baritone voice.
All jokes aside, he really is a wonderful singer.
RODAY: Yes, I totally agree with that.
He was going to lip-synch it to another mans voice.
It was going to be like a gag.
I cant imagine that song not being performed by him, and piping in another voice.
It just would not have been the same.
So, credit to a non-singer for stepping up and going for it.
Its really incredible to see the level of support you guys have from your fans.
FRANKS: I think we did something really smart.
And so, we were able to drum up our own social media support from the stage of Comic-Con.
Our fan base supported us when we didTwin Peaks.
They supported us when we didClue.
This really seemed safe, compared to many of the things wed done in the past.
So, it was an itch that needed to be scratched.
It was the pinnacle of the show for me.
HILL: We were excited to do it, but it was daunting because were a basic cable show.
We dont have all of this extra cash flowing around.
We always fit within our budget, and I didnt know how we were going to do it.
It was a little daunting, but I was definitely game for it.
I said, You know what?
We always swing for the fences.
Lets go for it!
Which was the most difficult number to do?
RODAY: Id say it was probably the opening number, just because there were so many elements involved.
That definitely felt like the biggest challenge for me.
Luckily, we knocked it out on the first day.
Were going to be good.
Does every single regular cast member sing and dance in the musical episode?
HILL: Most sing.
One of us does spoken word.
RODAY: Yes, there was one cast member who got off without having to carry a tune.
FRANKS: And that was Corbin Bernsen.
But, it turns out that he really wanted to talk sing.
So, that was my bad and my failure.
HILL: We probably shouldve, but we didnt have the time to.
Which is your favorite number from the episode?
Its ridiculous and its heartbreaking, at the same time.
It has all the emotions that we hope to play on the show.
Its probably my favorite thing that Ive ever gotten to shoot on the show.
RODAY: Thats my answer, too.
Its really poignant for me.
ItsPsychridiculous, with this undercurrent of, Why am I touched by this?
I have no business being touched by this.
But I think it works to great effect, and its my favorite, as well.
Will this music be available for sale?
Weve just mastered the soundtrack.
Its going to be a digital soundtrack.
And I have to say that its my favorite album, of all time.
