I think it was about six years ago or so, they had a production in DC where all except two or three roles were played by congresscritters.
Daniels, Ron Holgate (RH Lee), and Howard Da Silva were in the Broadway production (among others), though Da Silva had a heart attack during the run and had to be replaced (which is why he isn't on the Broadway cast album). I do think that the film serves "He Plays the Violin" much better, since it obviates belting it out. It's such a delicious little piece of sexual innuendo.
At the back of the play there is a section about what Edwards and Stone went through to write the play. Part of the problem was that there was simply too much material. We're talking about an era of forward-looking, very literate men with pride in a turn of phrase. (For instance, the whole "Franklin did this. Franklin did that..." riff is a direct quote from one of Adams's letters.) So they found stuff that they could use because (ironically) nobody would ever believe that they had said it. For instance, what Adams actually said about the legacy of ducking the issue on slavery was that there would be war a hundred years hence. Edwards thought this was a little too precient and toned it down a bit.
