In 2007, officials of Rockford, Illinois honored Cheap Trick by reproducing the "Rockford" album cover art on that year's city vehicle sticker. On June 19, 2007, the Illinois Senate passed Senate Resolution 255, which designated April 1 of every year as Cheap Trick Day in the State of Illinois. In August of that year, Cheap Trick honored the 40th anniversary of "Sgt. Pepper's Lonely Hearts Club Band" by playing the album in its entirety with the Hollywood Bowl Orchestra, conducted by Edwin Outwater, along with guest vocalists including Joan Osborne and Aimee Mann.
