Psych - Season 6 - Casting News - Mekhi Phifer & Cheech Marin to Guest

Thanks to Bruce_F for the heads up.

Mekhi Phifer and Cheech Marin will guest-star in an episode of Psych, TVGuide.com has learned exclusively.

Phifer, who stars as a not-so-dead dead man on Torchwood: Miracle Day, will play Drake, a member of "Blackapella," the a cappella group Gus (Dulé Hill) belonged to in college. Drake comes to town to honor Deacon Jones (Up in Smoke's Marin), his mentor from childhood. But the deacon is shot while receiving the honor at the local community center, and the group steps in to help Shawn (James Roday) and Gus investigate.
