You're not alone. Pippin brings back memories for me as well. I wan't alive to see it's broadway run, but I was Pippin my Junior year of High school, and my girlfriend at the time was Catherine. So we just loved singing "Love song" together.
unfortunately, she was horribly injured in a car accident one week before the opening, and was in the hospital for about two months or so. We had a get a replacement Catherine, a girl with a very annoying church lady-type voice. you know- one that warbles for days. We all got through the show, and to this day, My ex (who is now my greatest and oldest friend) can't listed to Pippin, and I get a little weepy when listening to the album, but especially "love song"
"I'm an American, Damnit!!! And if it's three things I don't believe in, it's quitting and math."
