Yes, Marcia Ball for sure. We just saw her live in Feb and she and her band were "fantabulous". Her sax player is jaw dropping great. She sits at her keyboard, her long legs crossed in a long gown, and just plays and wails away. I died and went to heaven !! Wife liked it too but not as much as me !!
