I'm not positive about this one because I haven't seen Spamalot, but I just got the soundtrack yesterday and this lyric popped out:
You Won't Succeed on Broadway:
"People who can sing, and dance — often at the same time! They are a different people, a multitalented people, a people who need people, and who are in many ways the luckiest people in the world."
Funny Girl (People):
"People who need people are the luckiest people in the world."
Possibly a small parody, or a coincedence?
somebody hold me too close...
