Here lately I've noticed a ton of rock bands performing on these late night shows, and I'm not sure whats up with that, but I'm not even mad about it!

This past Monday night Janes addiction took it to the Letterman show and performed their song 'Underground'  which is off of their album The Great Escape Artist, which was just released last month.

Oh and the dancers in the background is lead singer Perry Farrell's wife!

Check it out!
