Btw, just a tidbit.
When I was in 11th grade my school had a fund raiser for St. Jude's Hospital. Students went to homes in neighborhoods to collect for St. Judes and whichever grade got the most donations won a ticket for a concert which included Chubby Checker, Frankie, Fabian and others (can't remember if Rydell was there.) It wasn't a Dick Clark event. I can't remember who sponsored it.
Anyway I was so excited to go BUT as it turned out, the concert was on the same day as my sister's High School graduation. I remember telling my mom "I don't wanna go to a stupid graduation. I wanna go to the concert."

My mom won and I missed the concert.
