Roberts was the only accomplished singer of the original cast, though David Canary, who joined "Bonanza" in 1967, had a background in voice and performed on Broadway. During Roberts' "Bonanza" years, he recorded "Come All Ye Fair and Tender Ladies", a folk music album which "AllMusic" calls "...the softer, lyrical side of folk music — pleasant and not challenging, but quite rewarding in its unassuming way." The album, released by RCA Victor and arranged by Dick Rosmini, is available on compact disc only as part of the fourth disc of the "Bonanza" 4-CD boxed set on Bear Family Records.
