Sure, of course go, what a great experience to have. A selection of arias is a nice idea versus a full length opera, for a starter.

Second vote for another time to go to a Gilbert and Sullivan (opera x musical). If you don't know them do a youtube for Modern Major General's song or Three Little Maids from School.

Speaking of opera I have noticed my DS will do almost anything I ask if I sing my request in an operatic sort of voice.
