Other mistake: When Bob and Phil sub in for the girls during their "Sisters" number at Novello's in Florida, they have only heard the song performed once and we are supposed to believe that they memorized all of the lyrics? Also, in the same scene, there is an "ooh!" after they sing the line ".the same in the rain or sun." Obviously, the men are lip-syncing to a recording made by the Haynes Sisters, but the sisters' live performance did not contain the "ooh!" so how did Bob and Phil know to do this?
