Pop vocalist Shelby Flint earned a big hit in 1961 with "Angel on My Shoulder." In the late '50s she was signed as a songwriter by West Coast publisher/writer Barry De Vorzon, who took her to Cadence, where "I Will Love You" (1958) flopped.
Flint then followed the folk boom, forming an acoustic trio before recording the Top 30 hit "Angel on My Shoulder" for De Vorzon's Valiant
label in 1961. The song also appeared on the first album by labelmates the Cascades
. She continued to record for Valiant
during the mid-'60s, when her most successful single was one of several vocal versions of Vince Guaraldi
's tune "Cast Your Fate to the Wind" (1966). During the '70s, Flint worked as a session singer for artists such as Batteau (1974), while De Vorzon found a niche composing television themes like "Nadia's Theme" (a U.S. Top Ten hit in 1976) and "Simon and Simon."
