Legalities in performing music

[OompaLoompa]

Thanks for the reply. I definitely was assuming I would need to legally own all CDGs I might use, but I am confused about the legality of even performing a copyrighted song, even if I were to accompany myself on piano rather than using a CDG or eliminated track. I am not clear whether royalties are only paid for recording and selling a copyrighted song, or if it includes performances as well, and who is responsible for paying the royalties. I have read that clubs which even play a song as background music are responsible for paying royalties for it. So if I were to sing a set at a club of standards and songs I didn't write, I wonder if I am responsible for getting a license with BMI and ASCAP, or if the club owner bears the liability.
