Not necessarily in order but I would want these songs live at a concert (even though the band hardly ever performs some of these:

Lay Your Hands on Me
You Give Love a Bad Name
Summertime
Wild In The Streets
Whole Lotta Leavin'
It's My Life
Bad Medicine
I'll Be There For You (Richie)
Born To Be My Baby
Bed of Roses
Raise Your Hands
Any Other Day
Have a Nice Day
Last Man Standing
These Days (Richie)
Dry County
Who Says You Can't Go Home
Runaway
Livin' on a Prayer
Wanted Dead or Alive
Blood on Blood
Wild Is The Wind
