The committee of five appointed to write the Declaration of Independence were: Franklin, age 70 (Howard Da Silva was 62 at the time of filming in 1971); Roger Sherman, 55 (Rex Robbins was 36); Adams, 41 (Daniels was 44); Jefferson 33 (Ken Howard was 27); and Livingston, 29 (John Myhers was 49). The lyrics of "But Mr. Adams" give the reason that Livingston can not write the Declaration is because "I've been presented with a new son by the noble stork", but Livingston actually had only two children, both daughters, and the elder was not born until 1780.
