As Requested* by 1lordthorpe, here's Helen Shapiro singing a version of Lesley Gore's hit, "It's My Party". Featured on her 1963 album, 'Helen In Nashville'.
The original recording of this song.
Cap Oldies.
Never released as a single (as far as I know) this is Helen's cover of the Lesley Gore hit.
From the LP "Introducing Helen Shapiro"
