The Dukes of September are Donald Fagen of Steely Dan, Boz Scaggs, and Michael McDonald. On stage together as part of the band for an entire evening, they sing their own favorite R&B tunes and classic rock classics, like material from the Grateful Dead, the Band, and Motown and Stax-era tracks. USA Today says, “All hail the Dukes of September. Veteran rockers Boz Scaggs, Donald Fagen and Michael McDonald form a soulful supergroup.”
