Well, I think I can find the Loaded Dog, now that a few more clues have been provided. I just trek on down Johnston Street following the hair of the dog.

Wonder what "floor spots" are and "running a blackboard?" Maybe it's a sign-up for those with running shoes...It does sound like the Loaded Dog is a better place to try singing than our favorite pub, the Press Room over in New Hampshire, a place where you have to crank up your voice several steps to be heard above the general roar, and then be heard no more for the rest of the evening while your vocal chords cool off.

Bob mentioned by PM a few nautical singers who hang out in Sydney. Any chance of hooking up with them? Are they card-carrying Mudcats?
