We were all set to cross “If I Can’t Change Your Mind” off the master list after Bob Mould came in and told us it definitely counted as a cover when he played it. But the list was still out with The Decemberists, who agreed to play a song after we badgered singer-guitarist Colin Meloy on Twitter. When they asked if the Sugar classic was still available, we figured it wouldn’t hurt to have another version. Where Mould went solo-electric (and sang the little guitar bit at the end), Meloy and his current merry band—minus longtime member Jenny Conlee, who is battling breast cancer—decided to go with the five-man-acoustical-jam setup, the second Undercover performer to do so. The band’s performance at the Aragon that night was fantastic, and likely its last concert around here for a while, since Mr. Meloy will apparently be concentrating on his writing career for a bit. (Wildwood comes out August 30.)
