I think here in the US we're used to it being a bit different than how it's done in the UK.

I believe this is true;
I can write a song here (US) & anyone can go on stage, anywhere & perform it & I'm not due any compensation or royalities. I cannot record someone else's works but I can sing them where ever I like without payment or permission.

I don't know how this goes for U-Tube. I don't evenb know where U-Tube is HQ'd out of but I'm sure that many American perfomers & non-performers see U-Tube as any American stage where they can sing anyone's material without needing consent or royality payment. I have only a couple things up at the moment but will have more up in the near future but so far it's all traditional stuff. The only one I'm thinking of is a song by Guy Clark & I'll be trying to contact him 1st before I plan anything.
