Mark in Wisconsin

One of my greatest concert-going regrets is that I failed to attend this one (3/24/72 South Bend, IN). I grew up in South Bend, knew all about the concert, but did not go! My little brother went. He was only 13 years old at the time and he still talks about it. So, if anyone out there has a recording of this one, I'd SURE be interested in trading for it. Please email me directly (MWilliams44@wi.rr.com) if you can help. Thanks!
