Hi I'm new here. A lot of my repertoire in not original. In the folk and classical genres it is standard to do what might be considered old favorites or performing a classical piece. I also do pieces from other countries. 
Other genres have very different codes of ethics in this regard. 
Am I ok doing these types of songs in the house concert performance world?

I think that I, as an attendee, would love to see that at a house concert! That way you get a cool new artist but can also sing along to songs you know and love.
