Where can I get Maurice Williams and the Zodiac (or Gladiolas) singing "Little Darling"?

A clip of "The Diamonds" singing it, sounding just like they did in their 1957 recording and the 1958 movie, was on TV, and there are youtube clips of them as young men and old men singing it, in the latter Maurice Williams taking over the b in an encore, but Williams and "The Gladiolas" put it on the charts before "The Diamonds" made it the first rock and roll song to be released on a 45 rpm, No. 2 on the charts only because of Elvis's popularity in 1957! The unpublicized down-side of the era was white singers stealing black singers' thunder.
