John Lock was in the choir room as much as the entire Glee cast!

The Music Producer and New Directions drummer joins Jenna and Kevin with some fun Glee scoop, including how he got the gig after one email, being a 19-year-old on a hit show, why the band members were not allowed to speak or sing, and admitting he never got sheet music before an episode!

Plus, John talks about DJing at Jenna's wedding and Naya Rivera's infamous Snixxmas Christmas parties … and the cast member who split his pants on the dance floor!
