More should understand that when you open venues up people will come and in greater numbers benefiting the entire place.

Then the venues have to get bigger to accommodate the extra numbers, and the expenses get bigger as a result, regardless of where the money comes from. Bigger amplification is needed because the extra people will be further from the sound source, and the inevitable steaming great pile of shit will be proportionately bigger.

Why don't you just tow a pot on wheels behind you? Or better yet wear astronaut pants.

That is indeed one solution, and no more absurd than the rest of your ideas. This, presumably, would apply to the (volunteering) artists as well?

You paint a wonderful picture, Conrad, and we can all look forward to seeing Carthy/Watersons performing for free in their shit filled astronaut pants, heading the bill at a three day hot summer festival. I bet they can't wait.
