Def Leppard To Open For Bon Jovi

This is just baffling to me. Def Leppard will open for Bon Jovi on a handful of European dates next summer. Def Leppard is a bigger band than Bon Jovi and that is most certainly true in Europe of all places! But whatever, shows are shows and maybe they all just want to hang together. Who knows. I sure would love to go to Sweden Rock someday. I am going to Spain and Italy next summer - but no shows planned!
