About 6 weeks ago, we replaced a member of our band due to ongoing issues with him drinking as well as some other issues that he has in his personal life which were making it difficult for him to focus on the music. A few months ago he cost us a gig and then at the next gig, he was not able to perform up to what is expected. We decided to replace him and I informed him that he would be paid for the gigs that he did including the last one. I have reached out to him several times to try to make arrangements to get his money to him, but he has not responded. He mentioned that he was planning on moving to another part of the country and none of us know his present or former address. So my question is, at what point do we stop trying to get the money to him?
