Sorry for the delayed response Richard. Yes. Absolutely I know Demmer! I met him through Mark May. Eric played the magnificent sax part on Mark's most famous song "Call On The Blues" on his first album. STILL my favorite Mark May track. He is like family to me. I helped him do some promo stuff once too. They are a smokin' hot outfit to be sure. And Evelyn Rubio? Soooo bad azz! Anyone who hasn't seen them, and gets a chance to...do it! They have a new residency at a club downtown (Houston) called 'Venue Houston'. Wednesday nights.
