After an exhaustive search, "Peggy Sue Got Married", which was released in 1959, I could not find anywhere where the song charted.
Any time there are answers that are repeated, they are researched to make sure all the correct answers are accounted for.
As far as the John Travolta answer, "Take A Chance" could not be found on any chart, any where in my resources.
I use Alaska Jim's Music charts, which contains several different charts, which can be viewed by week, year ending, by single, by album, any way you want to look at music. I couldn't find the song anywhere.
Thank you, Gina, for your input. As far as you winning back in April, Ross, I am not sure what the rules are regarding this. This is my first month running the quiz, and I am not sure of the history of the winners. I will have to check with the big boss.
