Here's a transcript from the original airing of the POE show in 1991 (the one about to release might not have all of the same interview snippets)

But Dennis was the creative leader of the band at the time and it was really his voice and his writing that had given us our hit records to that stage. And I was vocal in some ways about the way I felt this was maybe not the right thing for us to do, because I had felt we would reach our first peak when we had a hard rock song that was actually a hit, which "Renegade" and to some degree "Blue Collar Man" as well gave us that. I was very concerned about "Babe" because I was very scared that "Babe" would alienate the audience that we had built. And of course it didn't do that; it took this band to a new level, and indeed 1979 was the year, and I'm sure partly as a result of "Babe" and partly as a result of our career history up to that point, we were voted #1 rock band in America in a Gallup poll.
