This was originally called "Backwards." Justis changed the title when he heard someone enjoying the tune say that it was "raunchy," which meant "good" in '50s teenage slang.
Ernie Freeman covered this. It was a reversal of the usual process as Freeman was black and Justis was white. Freeman's version hit #4 while Justis' hit #2. Although both did extensive session work, "Raunchy" remains each act's sole Top 40 hit. (thanks, Brad Wind - Miami, FL, for above 2)
George Harrison played this on his guitar for John Lennon when he was auditioning to be a member of The Quarrymen.
