 Some characters were changed in the transition from the stage. The  original musical features only Charlie Brown, Linus, Lucy, Patty,  Schroeder, and Snoopy. In the animated adaptation, Patty, no longer  familiar to modern viewers, has been replaced by Sally. In the 1999  Broadway revival of "Youre a Good Man," that change was kept  (though Marcie, Peppermint Patty, and Woodstock also appear briefly  as well, even though they arent in the original).
