The choreography by Mary and Lynda is way too busy for Jean’s mid-tempo lead vocal. While it worked very well for the faster version on the Flip Wilson Show it is jarring here.

Did they lip-sync to the record when originally broadcast or was the recording later added to the video by the YouTube poster ?
