Here's a video of Bob Mould covering Cheap Trick in Chicago. The video features Bob and the band doing "Downed" followed by the Husker Du classic "Celebrated Summer". When I caught Mark Kozelek a while back, he performed his cover of "Celebrated Summer". Ever so slightly different from Bob's/Husker's version.
And I just saw this great video of Bob and the band rockin' out on "The Descent".
