Old rocker here as well.  The first concert I saw was The James Gang opening for Santana.  I have also seen the Edgar Winter Group, REO Speedwagon before they sold out and became a chick group, Stephen Stills, T-Rex, Lynyrd Skynyrd, AC/DC, Spooky Tooth, there are more, but the mists of time have obscured them from my memory.  Iron Butterfly used to play at a biker bar all the time on Cleveland Ave in Columbus Ohio, but I cannot remember the name.
