Not exactly a show, but yes, a stage in front of 500 people. I read a passage of poetry from Ovid's Metamorphoses, in Latin. It was approximately 17 lines, and I spent 5 months preparing it. The good news is that I can now sight-read, in proper meter, any Latin work written in dactylic hexameter.
Other than that, I can't do stage because, while I'm excellent at dialogue, I fail at monologue. I'm not in the drama stream at my school, so any dramatic thing I could do (for class projects, extracurriculars, etc.) is either one-liner or LEAD ROLE, so I'm kind of stuck. Ah well.
