I was watching some downloaded bootlegs but this one in particular made me wonder..
It was Keep the faith and Bed Of Roses "Live" '93 Countdown, Holland. Something like that.
At first I thought "wow! Jon is singing amazing the keep the faith chorus" but then I started to get suspicious.. and it seemed to me that they used playback for the chorus ("You know you're gonna live.. etc") and for the backing vocals.. but evertything else was live.. If any of you have the video please tell me! I wanna know!

That version of Keep The Faith (If real..) is absolutely amazing.
