Going into Hamilton Blind
If they have strong preferences one way or the other, I would support them. Otherwise, I would encourage them to listen to a few of the faster paced sections and see if they want to hear more or leave the rest until the performance. I saw it once without any pre-listening and again when I knew the show practically by heart. I loved it the first time but enjoyed it even more the second time. I hope you all have a great time! It's a wonderful show!
