Clip one: Originally there was going to be a rap number during the Delores DeLago segment featuring a turned over wheelchair as a DJ table (genius!) and the Harlettes acting like gangsters. Unfortunately this number was cut at the last minute, but luckily this footage exists from a dress rehearsal that shows what this segment would have been like.
Clip two: Bette and the Harlettes try on their new mermaid tails for the first time during this dress rehearsal only to discover that there is no rubber on the bottom to keep them from slipping on the stage. Bette suggests a strange remedy, but apparently this is indeed a trick of the trade.
