'Psych: The Musical' To Air On December 15 (VIDEO)

Set under the sunny Santa Barbara sky, Shawn (James Roday) and Gus (Dule Hill) showcase their musical talent in the trailer (above) for the two-hour episode, airing on Sunday, December 15.

First announced last summer, "Psych: The Musical" has been a long time coming ... but Hill, who got his start as a tap dancer, hinted to The Huffington Post that it will be well worth the wait.

"There's ... so much more going on with the musical episode, and it took 14 days to shoot two hours' worth of television. I do dance for a little bit, but it's not a whole tap number," he teased.

"Psych: The Musical" will air on Sun., Dec. 15 on USA.
