Thurman Carthen has been a custodian at the same high school for 13 years. As a passionate and talented singer, he would sometimes take a break from his daily duties to sing happy birthday to a school staff member.

He was unaware, however, that the students paid any attention to his musical abilities – which is why he was so touched that the youngsters asked him to sing at their graduation ceremony.

Carthen was especially emotional over the request because he is retiring from his long career at Galena High School in Reno, Nevada next week.
