All of us here at GATRS stayed up late last night to catch our latest obsession, Catfish and The Bottlemen make their U.S. television debut on the Late Show with David Letterman Show last night.
The band sang Kathleen, off their album the Balcony which is finally now released stateside.
If you are in the land of Oz, you can catch them opening for The Kooks this month before heading back to the states for their own headlining tour.
We will be at several of their shows to bring you all the live action.
Watch Kathleen below.
