If your brother and ex-husband recorded music in the 60s, they may not have received payment due to various reasons, such as not having a formal contract, the record label not distributing the music widely, or it being a low-budget or independent project. Additionally, royalties and rights issues can complicate payments, especially if the recordings were never properly registered or if the label went out of business. It's important to consult with a music rights expert or lawyer to explore any potential avenues for compensation.
