Roger Waters made a rare tv appearance on Conan on Wednesday night.

There were moments of fun and serious talk through the interview and, naturally, much of the conversation was based on The Wall and Roger's current tour.

Waters spoke of his original inspiration for the concept album, its relevance today and its influence 30 years after its release.

As for the tour, there was talk of Roger meeting veterans backstage during the show’s intermission, as well as his support the local music groups that accompany him for “Another Brick In The Wall, Part 2.”

Waters wrapped up his current US dates of The Wall Live tour on Wednesday with a concert in Anaheim, California, and now heads off for three dates in Mexico City before taking a break for the seasonal holidays.
