After conducting a thorough search, I could not find any information on a musician named Captain Newman. It's possible that the name refers to the 1963 film "Captain Newman, M.D.," starring Gregory Peck, or to other individuals with the surname Newman, such as composer Randy Newman or musician A.C. Newman. If you have more specific details or context about the artist you're referring to, please provide them, and I'll be glad to assist further.
