Let me guess, in the harshest of Aussie winter, it gets a bit chilly? :P
Yes, you definitely must. It would go great with your glasses. Everyone should have at least one leather jacket in their closet, I believe.

Hmm, Halestorm, though I don't remember exactly which tune. This one, I think (a cover, but a good one). I've been listening to them non-stop for a few days now, they're great.
