Check out this brand-new promo for “Psych: The Musical,” exclusively here on Zap2it first. The voiceover guy even gets in on the singing act!

We’re also delighted to see some more Gus dance moves and hear the dulcet tones of Lassiter flexing his golden pipes — “let’s review how we do a tried-and-true investigation.”

Shawn says, “This might sound crazy, but I think we can pull this off.” We never had any doubt and we can hardly contain our excitement for the musical extravaganza.

Below, check out the call to “Psych”-Os to show off their best dance moves in preparation for the special two-hour event. Entries accepted until Dec. 1.

“Psych: The Musical” premieres Sunday, Dec. 15 at 8 p.m. ET/PT on USA.
