OK, back to the 50's: Sammy Fain and Paul F. Webster wrote this romantic 1955 classic as the theme for a movie sharing the same title. It won the Oscar for Best Song. A Philly-based vocal quartet recorded the best-selling version. It topped the U.S. charts and peaked at #2 in the UK, becoming their signature tune. Part of the "Grease" movie soundtrack. Song? Group?
Yesterday's answer: "Moments To Remember" by The Four Lads. From Adrienne Adams: "You started me off on a Wikipedia treasure hunt, where one page leads to another and I found out that "Istanbul (Not Constantinople)" was a hit for them in 1953. I never heard it before They Might Be Giants. I love learning new stuff."
