There is an "onstage blooper" on the DVD where Carol Burnett stopped the show because her skirt had not been fastened properly and was starting to slip. Fortunately for viewers, it occurred during a show while the cameras were practicing for the performance they would actually record, and it was caught on tape.
"Do I Hear a Waltz?" is the only song in this production where Stephen Sondheim only wrote the lyrics. The music for that show was written by Richard Rodgers.
