Mick Jones and Lou Gramm both have health issues- that's why the current touring version of Foreigner doesn't have any original members in it.
Don't like that? Then don't go see em. BUT - know this- nobody leaves that show unsatisfied. The touring band was picked by Mick Jones himself - and sells out venues EVERYWHERE. THAT'S how good they are.
Regardless- I think it's pretty cool that they all got together to honor the other members.
I wouldn't expect much more of this though.
