Rainwater got his big break in the music business when he performed on Arthur Godfrey's programs. He won first place on "Arthur Godfrey's Talent Scouts" on May 9, 1955. He had a regular role on ABC-TV's "Ozark Jubilee" for several years in Springfield, Missouri beginning in 1955. He signed with MGM Records and recorded a series of songs for the label, including peppy numbers like "Hot and Cold". Such songs were showcases for Rainwater's voice, and his energy and versatility led him to record rockabilly.
