Though Widespread Panic’s official Halloween show will take place at Chicago’s Aragon Ballroom tomorrow, the group dotted its setlists at the Chicago Theatre with some rare material and special covers over the weekend.

On Friday, the band played Chicago blues icon Muddy Waters’ “Baby, Please Don’t Go” for the first time since October 31, 2008 and inserted a “Not Fade Away” jam before their drum segment (Panic had not covered “Not Fade Away” since the ’80s before this weekend). Then, yesterday at the same venue, the band busted into Professor Longhair’s arrangement of the traditional “Stag O Lee” for the first time since November 4, 2007 early in the show and gave a shout-out to Bloodkin before covering their “Can’t Get High” second set. Finally, at the end of their gig, Widespread Panic ran through the Doors classics “Peace Frog” (which references Chicago) and “Blue Sunday” for the first time since November 28, 1998. Panic debuted the songs on Halloween in ’98 and have only played the covers a few times since that night.

Complete setlists for both shows are available in our Box Scores section. Panic will celebrate Halloween at the Aragon tomorrow.
