Lawrence Welk
The show had a "bubble machine." Whenever the orchestra played a polka or waltz, Welk himself would dance with the band's female singer, called a "Champagne Lady" on the show.  His first Champagne Lady was Jayne Walton Rosen (her real name was Dorothy Jayne Flanagan). Rocky Rockwell would usually sing novelty songs. Welk would also have one song each show where he would play an accordion solo.
