While he had not yet had a hit record for RCA Victor, his stature was growing. He began assisting Sholes as a session leader when the New York–based producer needed help organizing Nashville sessions for RCA Victor artists. Atkins's first hit single was "Mr. Sandman", followed by "Silver Bell", which he recorded as a duet with Hank Snow. His albums also became more popular. He was featured on ABC-TV's "The Eddy Arnold Show" in the summer of 1956 and on "Country Music Jubilee" in 1957 and 1958 (by then renamed "Jubilee USA").
