 The new classics?

Though the singers all acknowledge their debt to that period, they differ on whether it represents the last great hurrah for American pop music:

Scaggs: "Music is everywhere today, it's moving very quickly, and it's very segmented, so it's going to be very hard for classics to emerge, songs that wear into people's soul. There will be classic songs to come out of the past few decades, but they won't have the resonance of the songs of the '60s and '70s."

Fagen: "There is nothing close to it now. Black popular music at that time all came out of the church -- gospel was the root. Although some black singers (today) may start singing in a church, it's a different church. The music sounds more like pop than gospel. ... If there is any more powerful music than soul music and straight gospel music, I don't know of it."

McDonald: "No, the '70s wasn't the last great era. What's happening right now will, in hindsight, become much more important to people. I didn't appreciate the '70s then as much as I do now. And the '80s -- I wasn't a big fan until now."
