Interesting:
Scene Three of 1776 holds the record for the longest time in a musical without a single note of music played or sung – over thirty minutes pass between "The Lees of Old Virginia" and "But Mr. Adams", the next song in the show. On the DVD commentary, Peter Stone says that he experimented with adding various songs in this section, but nothing ever worked. During this scene, dubbed "Big Three" by cast members, musicians were allowed to leave the pit, reportedly the first time in Broadway history that they were permitted to do so in the middle of a show.
