That's it for me in a nutshell. It doesn't matter who you're talking to or what you're talking about. Every cell in your body is suddenly telling you "Stop this now, get out there and dance". It often just takes the first note and I'm away with the missus trailing in my wake. She's used to it by now.
I also like that feeling you get when you go to a venue you haven't visited before and you get there early doors, enter the big room and do the mental checklist: plenty of interesting looking record boxes, big, proper dance floor; big, long bar with lots of people ready to serve, lot's of good sitting space, vaguely remembered nice tune playing, friendly faces all around - woohoo
