Hair

Mention you've gone to see a performance of Hair, and inevitably you're asked about the infamous scene. We're not ruining anything for you in the largely plotless show by telling you that yup, the folks in the current revival of the 1967 musical do go pantless at the end of the first act (although, as usual, we were too far away to see anything). So, yes, there's nudity on Broadway. There's also lots of simulated sex, ultra-singalongable songs about free love and drugs, and an overarching message that long hair and peace will never go out of style.
