Tickets for the show must be totally non-transferable, so the only way to get in will be to meet the person with the tickets and walk in with them. Stubhub does offer tickets in this category, but have no idea how they go about organizing the meet up between the buyer and seller.
Personally, I'd be pretty skeptical about buying tickets that require meeting up with the seller, but who knows. Maybe they'll be legit and show up!
