The making of Be my baby (The Ronettes/Phil Spector)

Funny, Wikipedia says ' Ronnie Spector is the only Ronette to appear on the single' and 'The Blossoms, led by Darlene Love, and Sonny and Cher were part of the group of guests that provided additional backup vocals.'.( https://en.wikipedia.org/wiki/Be_My_Baby ) Maybe those images are when all three of the Ronettes were in the studio at another time? (Or Wikipedia has it wrong, instead.)
