Following Umphreys McGees performance at Madison, WI’s Orpheum Theater, Brendan Bayliss and Kris Myers ventured next door to see former New Groove of the Month Groovatron perform at the Stage Door Theater and, of course, jam a bit themselves. During ‘Bone Diggin’, at the end of Groovatrons set, guitarist Marc Quagliara moved to a small keyboard set up to make room for Bayliss, who performed on the groups original composition. Also, during its encore, Myers replaced Groovatron drummer Andy Dumeresq for a cover version of Mardi Gras anthem Cissy Strut. Umphreys McGee will take the stage tomorrow at New Haven, CTs Toads Place while Groovatron is off until its February 17 performance at Michigan City, INs Shoreline Brewery.
