This summer, Roger Waters will embark on his latest tour. It’s called This Is Not A Drill, and will take place in-the-round at a bunch of giant venues around America. Last night, he stopped by The Late Show With Stephen Colbert to promote it.

While Colbert introduces the performance as a medley of “The Happiest Days Of Our Lives” and “Another Brick In The Wall Pts. 2 & 3,” that’s actually the classic rock radio standard version that everyone just calls “Another Brick In The Wall.” Now, Waters has played that song a lot. But on Colbert, he sounded pretty great, and there was a proper amount of groove and fire behind the performance. To be honest, it made me actually want to see Waters’ endless touring behind all the old Pink Floyd hits.
