It Hurts To Be In Love (Howard Greenfield-Helen Miller) by Gene Pitney
Co-written by Neil Sedaka’s regular writing partner Howard Greenfield, this was originally recorded by Neil (listen here: https://www.youtube.com/watch?v=fXGAeAm2nZo ) but not issued by his label RCA Victor due to contractual issues. For Gene’s release, he was given permission to utilize Neil’s existing backing track while substituting his own lead vocals (see the story at this Wikipedia site: https://en.wikipedia.org/wiki/It_Hurts_to_Be_in_Love )
