Def Leppard frontman Joe Elliott said that the band pushed the release of their upcoming covers album from last fall in order to keep it from "falling into obscurity." Entitled Yeah!, it will now be released on May 23. "We wanted to put it out, tour (to support) it and make it a legitimate record rather than just some throwaway thing," Elliott told Billboard. "And we were kind of happy with the way it turned out. Essentially a covers album is supposed to be about fun. It's revisiting your youth and showing the world where your true roots are. It shouldn't be a labor of love." Def Leppard will kick off their summer tour with Journey on June 23 in Camden, NJ.
