Waters discusses a variety of topics with the host, including his relief and benefit work, plans for bringing his Wall tour to Europe, and how the iconic 1979 Pink Floyd album's message has changed over the years.

"The version of The Wall that I'm doing now differs from the one that I did with Pink Floyd in 1979, '80 in that it is far more universal in its message," explained Waters. "It's no longer about that miserable, self-serving, sniveling, nasty little Roger that we all hated all these years ago. It's more about ... rebellion that is trying to understand the world and, if possible, help people occasionally."

Stewart tossed Floyd fans a bone during the session by asking Roger, "Now, you're going back on the road with the remaining members of Pink Floyd, right?"
