Sir Paul McCartney hasn't forgotten about Tucson, you guys. In honor of Throwback Thursday, the legendary Beatles member tweeted a photo of himself cutting into his Birthday cake backstage at the Tucson Convention Center. McCartney says this picture was taken on June 18, 1976 during the "Wings Over America" tour.
Paul left his ranch in Tucson, Arizona for some California grass. Get back, Paul. Get back to where you once belonged.
