I saw Robert Plant and his earlier band The Strange Sensation at the MSG a few years ago when they were touring with The Who. Robert Plant was promoting his then newly released Dreamland album. That was a great show - Robert Plant played an encore of Whole Lotta Love, introducing it as a blues song! The Who played all their favorites.
cool! :-) I'm sure you've checked out "Still loving you" and "Winds of Change". I started following the Scorpions quite recently myself (about three years ago). I'm a big fan of their rock ballads - they are amazingly intense!
I often listen to Quadrophenia when I exercise.
