Yes, I am in the U.S... Tucson to be exact (a hot bed of traditional music ascap infringement). I have a friend who is an ascap member, but has purposefully not registered various songs, including one she wrote for us, with ascap. She is also a lawyer and a law professor in fact. She is going to check with ascap and make sure we can play it. I will let you know.   

We were very careful on Friday and we talked about where we got material on stage, so I think we are ok. However it limits the songs that I can sing, so I will be doing more research and learning pre-23 songs for a while.

Thanks for all the great resources.
