From Rolling Stone:
When King submitted a demo of this song to the Tokens — the production team behind the Chiffons — they wanted to release a single immediately. “But I can’t sing,” King said. So the Tokens kept King’s music, erased her voice and added vocals by this group of Bronx high schoolers. A year later, the girls were on the road with the Beatles. King got sweet redemption in 1980, when her own version reached the Top Twenty.
