On 1960-05-30, two singles titled "Alley-Oop" broke into the Billboard Hot 100: one by the Hollywood Argyles, the other by Dante and the Evergreens. They reached their peak positions, #1 and #15 respectively, in the same week as well: 1960-07-11.
A third version by the Dyna-Sores premiered the week after the first two (1960-06-06), but it peaked at #59 and lasted only three weeks.
All three versions are about the comic strip character, have virtually identical lyrics, & are in the same style.
The old gatekeepers of music made it complicated. The answer is half of Skip and Flip: https://en.wikipedia.org/wiki/Alley_Oop_(song)
Which is the original, and which are the covers? Or are they all three covers of a single that never made it onto Billboard's charts?
