I went to a small, vaguely religious, liberal arts school and one of my classmates who I didn't know well but was friendly with was heading to medical school after college. During our graduation ceremonies, he surprised most by leaving the student section and taking his seat behind the organ at the church our ceremony was in and just slayed the ivories (are organ keys called ivories?). It was phenomenal. After the official program, he was just messing around playing popular music and shooting the shit with everyone for another hour or two. It turned out he was a biochem major, chemistry & liturgical organ minor. Pipe organs seem like such magical instruments, I'm always shocked when I meet someone who can play one.
