I have a related question. I coordinate an open mic for a non-profit acoustic musician org in Seattle (Victory Music) at a restaurant. Neither performers or restaurant gets any money. Cover charge for non-performers goes to Victory Music. The restaurant is licensed with ASCAP and BMI, but recently received letter from SESAC saying they had to license with them also. I know nothing about SESAC - who do they represent? Most of our performers are singer-songwriters who do their own stuff, but sometimes people sing covers. What should I tell the restaurant owner?
