rca victor 47-6518. "you're the apple of my eye" was a last-minute substitution for another song that frankie valli and the group was preparing to do in the recording session, "don't be cruel". accounts differ as to the precise mechanism behind their "not" recording the otis blackwell song. some sources indicate that the four lovers were told not to record the song as elvis presley expressed a desire to record the song himself; other sources indicate that blackwell himself requested that the four lovers not record the song so he could "shop around" for a bigger act (and a better royalty deal) for the song (and succeeded when presley's manager approached blackwell with the idea of presley recording "don't be cruel").
