Following in the path of Buffy the Vampire Slayer, to name one example, Psych presents a musical episode. In this case, it’s a two-hour, stand-alone made-for-TV movie, in which Shawn and Gus (James Roday, Dulé Hill) strut their song and dance moves, along with a supporting cast of singers and ringers, including guest star Anthony Rapp from Rent.
