At the start and end of each episode, lyrics to songs were shown at the bottom of the television screen, hence the
Sing Along title, but no bouncing ball on television. (There was a
bouncing ball going over the words in the theatrically-released
Screen Songs and
Song Cartunes cartoons.) Three of the singers were given comedy segments in the series, as of September 1961. Ken Schoen, Hubert Hendrie, and Stan Carlson were known as The Vocalamities.
Bob McGrath, a tenor who later played Bob Johnson on
Sesame Street from 1969 to 2016, made his television debut on this show as one of the soloists. Miller also gave solo singing spots to baritone Keith Booth as well as female singers Diana Trask, Mary Lou Ryhal, and
Leslie Uggams among others. Musical specialties were played by pianist
Dick Hyman or accordionist Dominic Cortese. Later shows also benefited from occasional guest stars like
Shirley Temple,
George Burns, and
Milton Berle. They would perform songs they had popularized over the years, joined by the sing-along gang.
Mystery guests In later seasons, the male chorus was supplemented by unannounced mystery guests in the sing-along finales. Celebrities were paid $500 for participating: among them
Ray Bolger,
Red Buttons,
Johnny Carson,
Wally Cox,
Buddy Hackett,
Jerry Lewis, and
Joe E. Ross (in his police uniform from the
Car 54, Where Are You? series). Only former United States President
Harry Truman turned down the offer in the first season.
Frank Lovejoy appeared in one finale, but died before the episode aired. A new finale was recorded and aired. ==Production==
