I say that as if I really care about Band From TV, which you might recall (unless you’ve been fortunate enough to block out that Idol Gives Back “Before He Cheats” performance) features actors James Denton, Greg Grunberg, Jesse Spencer, Bob Guiney, Bonnie Somerville, and Teri Hatcher. But here’s the thing, I just watched this crappy clip (below) from a recent Netflix LIVE! On Location event in Los Angeles, where Chuck’s Zachary Levi joined the group to duet with The Bachelor’s Guiney on “The Letter,” and I found myself actually wishing the sound quality was better.

Apparently, Hayden Panettiere, Adrian Pasdar (even hotter holding a guitar!), and Jorge Garcia also jam with the band. Watch Garcia take on “Mustang Sally” after the jump. Is he decent, or is that just a song it’s impossible to screw up? (Note: Turn your volume down. Hayden’s a screamer.)

See Zac singing “The Letter” a song written by Wayne Carson Thompson, at about 3 minutes into the video.

Big Thanks to Linda for the link!

UPDATE: heres a better video of Zac singing:
