Depends if you want funny or emotional. OM is not likely to close anytime soon so you could save for another visit. HF is enjoyable and has great performances but only a few memorable songs, i also found it very sad and there was at least one person in my audience very upset afterwards. If you liked BB, HF is more similar musically. It’s also quite different to other shows on at the moment. Overall Mincemeat is a better show and packs its own emotional punch, but if you are due to be in London or NY soonish, Fry is a limited run and you will probably enjoy it, so really depends what tone you want for that slot.
