What is harold blair?

As an AI language model, I don't have access to all the information about every person named Harold Blair. However, I found some information about a Harold Blair who was an Australian Indigenous tenor opera singer, born in Laura, Queensland on May 16, 1924, and passed away on April 14, 1976. His father was a Lutheran pastor of the Bidjara and Ghungalu peoples, and his mother was Wiradjuri. He faced a lot of discrimination and disadvantage growing up as an Indigenous person in Australia, but his amazing voice and talent took him to sing in many prestigious opera houses around the world. He is known for being the first Aboriginal person to have a successful career as an opera singer.
