The punk-rock legends are back and are better than ever.

On their comeback trail they played the Aragon Ballroom in Chicago and when Billy spotted a seriously enthusiastic fan in the front row pit...and he had an idea.

He asked the young fan to get up on stage and prove his geetar skills.

Well, this lad absolutely killed it.

He started by launching himself up on the monitor and then just flew!

This is the stuff of your teenage rockstar dreams.
