Last night, CBS’s 60 Minutes profiled former Pink Floyd frontman Roger Waters, discussing, among other things, his mega-successful “Wall” tour.

Waters spoke with CBS’s Steve Kroft about the enduring appeal of Pink Floyd’s The Wall album: “I think it strikes some chords that may be just beneath surface in most of us. What it’s about, is the walls that exist between human beings, whether… on a family level or on a global level. And I think that resonates with people.”

As for the incredible amount of work that went into producing the concert — it took about three years of development before the first show hit the stage — Waters said, “The emotional payback is enormous. The truth of the matter is that the work is the reward. I mean, the shows are great. Don’t get me wrong. I love the shows…But I love…the nature of putting the thing together, you know. I like not just the nuts and bolts, but I like the process of trying to work out how to make it better all the time.”

You can watch the segment here. If that’s not enough Roger Waters for you, he recently posted a video on his Facebook page that showed behind the scenes footage of his now-famous stop on “The Wall” tour at England’s O2 Dome from May of 2011, when he was joined by his former Pink Floyd bandmates David Gilmour and Nick Mason.

The U.S. leg of Waters’ stadium tour kicks off tomorrow night at the Rose Garden in Portland, Oregon.
