“Psych” has a treat for you airing Wednesday night (May 29) during the season finale — the first promo for the musical event. But get an advanced look here first at Zap2it.

There aren’t too many details given away during the teaser trailer, but we did spot a dance number on the pier, complete with Gus being hoisted on the shoulders of some dancers, plus a fun tableau of Shawn, Juliet and Lassiter on a staircase somewhere. Exciting!

“Psych” Season 7 is just about wrapped up, but the musical will tide us over this winter until Season 8 premieres — which will feature the returns of Cary Elwes and Kristy Swanson, plus an episode remake. The musical premieres December 2013.
