I liked Altar Boyz a lot but I think that if they don't get to New York very often then that might not be my number one choice.
I would definitely reccomend In the Heights, I think that show speaks to a wide audience. Hairspray is good but I'm not sure if the grandson would go for it? I don't really know his taste. Spamalot might be a good option, but again I don't know his sesne of humor. SOrry I couldn't be more helpful.

Cages or wings?
Which do you prefer?
Ask the birds.
Fear or love, baby?
Don't say the answer
