OK, back to the 40's: The Three Suns put music to Buck Ram's (now, that's a manly name!) lyrics and first recorded this romantic ballad in '44. Les Brown and Jimmy Dorsey released covers the following year. By far the best-known "updated" version is by The Platters, which topped both the Pop and R&B charts in '58.
Yesterday's answer: "(Who Wrote) The Book Of Love?" by The Monotones. The "boom" sound was accidentally recorded when a basketball hit the studio wall - they decided to keep it!
