He forms a singing duo with Lynn Powers early on, signing a contract with her. When they sign to front Jock King's band, success immediately goes to Weaver's head and he becomes a hard-partying, demanding jerk. Still, Powers loves him, and wants to marry him even though he initially seems totally disinterested.
When Weaver jilts Powers at the altar, she freaks out so bad she wakes up in a hospital hours later with no memories of how she got there.
King steps up to take care of her, and kinda takes advantage of her vulnerable state to ask her to marry him!
She does, but only because she feels obligated. She soon hears unpleasant rumors that King only does charity gigs for the free publicity, and he bought out her contract with Weaver and married her just to keep her as his singer.
Weaver gets in an accident just as King and band have to brave dangerous, snowy mountain roads to get a charity gig.
Weaver, on his deathbed at the hospital, tells Powers the truth: King didn't buy her contract from Weaver, King paid Weaver to cancel it. King thought Weaver was dragging her down.
