Ok, well then what you mentioned would probably be easiest. Do you use a mic to address the crowd or anything? Or does the club have one up to announce acts or anything? It's just that, if you don't have a single mic, people won't really be able to hear that the set is live. It'll sound like a studio recording. Unless it's just the set in general that people want.
If you're going to be doing more live recordings in the future, and you don't have a whole lot of money to spend (like me) maybe you could pick up a pair of these.

They're very inexpensive for condenser mics, and they sound pretty good on a room. They're cardioid, so you could place them in the same location pointed about 90° apart, or you could space them apart. Whichever sounds better.
*EDIT* Not to mention they look pretty badass.
Also, I would strongly suggest recording directly to an external drive. It'll tax your laptop less, and, for a long recording, it's essential that nothing go wrong.
