I'll Be You
Armstrong has often referred to the Replacements' Paul Westerberg as a "hero," and so when Westerberg was grounded with back pain for the Minneapolis legends' reunion gig at Coachella on April 19th, 2014, the Green Day frontman was only too happy to come to the rescue. Armstrong, who once recalled seeing the Replacements perform in 1987 all dressed in plaid, came on stage at Coachella – in a plaid suit, natch – and backed up Westerberg as the 'Mats singer reclined on a sofa. Armstrong provided similar support at various festival gigs through the summer. Was he psyched? Before playing the Forecastle Festival in Louisville, Kentucky, Armstrong uploaded a photo of himself with Replacements bassist Tommy Stinson to his Instagram account with the hashtag, #holyshitIminthereplacements.
