Adam Lambert will cover The Darkness on 'Glee'

Adam Lambert is no stranger to over-the-top glam rock, so covering The Darkness (as Lambert does in this week's episode of Glee) is right in the former American Idol contestant's wheelhouse. Lambert took on their surprise 2003 hit "I Believe In A Thing Called Love" during his appearance on this week's episode, "Frenemies."

Lambert takes on the track alongside Chris Colfer as the two face off in a guitar shop. Check it out in a sneak peek below:

Of course, it doesn't hold a candle to the hyper-kinetic and addictive as sugar original.
