From 1952 to 1957, he was best known as a vocalist on Your Hit Parade, an NBC television series that reviewed the popularsongs of the day and on which a regular cast of vocalists would perform the top seven songs of the week. Arms and Eileen Wilson (who starred on the show from 1950 to 1952) were the only surviving lead performers from the show until Arms' death in 2012. He authored an autobiography in 2005, My Hit Parade... and a Few Misses. During his career as a singer, he was also well known for his 1957 hitsingle, "Cinco Robles (Five Oaks)", which entered the charts on January 12, 1957 and stayed there for 15 weeks, peaking at No. 22. In 1957, he released the album Where Can A Wanderer Go, on the Era label. The same year he was a singer on The Hidden Treasure Show, "the first nationwide quiz show in which home viewers win the money...".[5] The syndicated program was sponsored by Disabled American Veterans.[5]
On television dramas, Arms made three guest appearances on Perry Mason, including the role of Attorney Everett Dorrell in the 1960 episode "The Case of the Credulous Quarry", and as Roger Correll in the 1963 episode "The Case of the Greek Goddess". Additionally, he appeared in the 1961 episode "Bad Sheriff" on the long-running series Gunsmoke, portraying a crooked lawman who tries to keep the money seized by stagecoach robbers.[6] For the next two decades he continued to act periodically in other television series, including the CBS sitcom Ichabod and Me in 1962 and the NBC drama Gibbsville in 1976.
A 1958 newspaper story about Arms noted, "Although Arms started in show business as an actor, he became a singer 'by accident,' and now he can't get anyone to believe he can act. 'I'm now in the process of proving them wrong,' he said."[7]
