Glee - Teenage Dream - Darren Criss and Beelzebubs

I'm very happy to learn that The Sing-Off's Beelzebubs were part of Glee this week. Though the group did not get any video time, they were the voices behind "Teenage Dream" with Darren Criss on lead vocal. How exciting! The single is going to have a huge debut on Billboard next week.

Beelzebubs were one of my favorites in last year's The Sing-Off on NBC.
