Fredianelli was born in Detroit, Michigan. He formed the Gaylords (originally The Gay Lords) with Bonaldo Bonaldi and Don Rea in Detroit in 1949. For a while he used the name of Ronnie Vincent before adopting the name Ronnie Gaylord.
In the military, he was assigned to Special Services and sang with a military band. He had one hit as Ronnie Gaylord: "Cuddle Me" (1954). (Apparently, he was allowed to release it while still in the service.)
In Feb 15 1955 he was discharged from the military at Fort Carson, Colorado and rejoined The Gaylords.
In 1976, Bonaldi changed his name to Burt Holiday, at which time the group became Gaylord and Holiday. Rea had left the group by that time.
He died in Reno, Nevada.
