I had an audio recording of a charity show that jovi did i think in 89,or90 at hammersmith odeon.jon and richie started off with 3 acoustic songs and did a three hour set with the rest of the band plus guest app.from jimmy page and others. i,m pretty sure they sang "we all sleep alone" which they wrote for cher and loads of their own plus other covers.although it was an audience recording the sound was perfect,and this was before digital!
