Umphrey’s McGee returned to Chicago’s The Riviera Theatre for the second night of its New Year’s Run. Partway through their set, the members of Umphrey’s McGee debuted a cover of Yes’ “Roundabout.” As previously reported, a night earlier the band added Steely Dan’s ‘Peg” to its rotation. Umphrey’s McGee will close the year at The Riviera Theatre tonight.
