The king of longevity was Bill Tapia, who was still touring nationally at age 103. At that age, he had been a pro musician for 85 years. Bill lived in California, but I saw him perform in New York City shortly before his death in 2011. As a ukulele player, he waited many years for his time to come, along with the recent increase in ukulele popularity (Iz, Jake Shimaboukuru, ect).
Although not famous except in uke circles, he played for the troops in WW1. He went on to perform with Bing Crosby, Louis Armstrong and Elvis. Bill, when he was about 102, told me he had just bought a house in CA and acquired a 30 year mortgage! He was quite a guy.
