Are you talking about their current tour for Beethoven's Last Night? I have tickets for the New York concert in May.
TSO is an AMAZING Christmas show. I have high hopes for this concert. The venues seem smaller, more like where they used to play before they got huge. I've seen their Christmas concerts umm... 5 times? They've started to get visibly bored of the Christmas music, so I'm pretty sure performing "new" material will wake them back up.
Their show is so lively, I don't think you'd miss anything going alone. I usually give up trying to have conversations with anyone I go with, unless it's by passing a text message.
Me? Obsessed? No....
