Yeah, I think they meant "things that my mom may not approve of", not "what is innappropriate for the stage".
Anyway, yeah, what people have said- strong language, homosexuality (may be shocking to some people, some conservatives may be offended by it), drug regerences, lots of sexual references esp. in La Vie Boheme and Contact. If you have the soundtrack, you might wanna ease her into it by playing the clean songs (i.e. One Song Glory) and then gradually easing in the more "inappropriate" songs from least offensive to most offensive. That's what I did w/my parents. :P
This is probably not the place to ask, and I apologize- I wouldn't do this unless I was dying for an answer, lol. Has anyone seen the current Broadway cast? Are they decent (not decent as in appropriate decent, decent in terms of their acting)? 'Cause I saw the tour and they were fantabulous, but I'm seeing it on Broadway and I'm worried I'm not going to like it, lol...
But now we have come almost to the end. One last step. And then, when I take power, they will be pulled down and ground into dirt for what they did to you. And what they did in so contemptuously underestimating me.
