Paul mentioned his "Litterenders" PSA. I remember that one, with Susan Reed singing, and Helen Hayes pleading "please do NOT litter."
As for Paul's ABBA intro, does "ABBA. Sounds neat to say, don't you think?" sound familiar?
But you forgot the best one--"Barry Manifold's 'Look's Like Tomatoes'", or did that one never make it on the air?
All these memories are great.
