Love, meanwhile, handled the lead vocals on the follow-up single, 1963's "Why Do Lovers Break Each Other's Heart".

Sheen and Love shared lead vocal duties on the final single, "Not Too Young to Get Married".

[1] Sheen can be heard as lead vocalist on the group's final recordings, "The Bells of St. Mary's" and "Here Comes Santa Claus", two tracks on the Spector-produced album, A Christmas Gift for You from Phil Spector (1963), on which Love also appears as a solo artist.
