During the late 70's it was decided that Betty Boop needed to be updated for the 下一个 generation. The original 动画片 were sent to Korea and were re-drawn and colored 由 artists there.
Betty Boop makes a Brief Apperence near the ending in broadway sitting at a 表 as a canine ( Helen kane caricature most likley) 唱歌 in a Betty Boop Style to the tune of Hello Beautiful. Most likley Little ann little singing.
