We are spending three weeks in LazyDays KOA Tucson AZ. The Jazz festival is 10 days but on Martin Luther King day it is free. There was an older Black singer with a great voice and he sang old standards. There was also a singer from spain that was very good but Linda did not like him singing in spanish. The back up people performing with him must have been locals pressed into service and they really were good. Especially the trumpeter.
