During the late 70's it was decided that Betty Boop needed to be updated for the suivant generation. The original dessins animés were sent to Korea and were re-drawn and colored par artists there.
Betty Boop makes a Brief Apperence near the ending in broadway sitting at a table, tableau as a canine ( Helen kane caricature most likley) chant in a Betty Boop Style to the tune of Hello Beautiful. Most likley Little ann little singing.
