If you have some time to kill, visit the Facebook Group called Hand in Hand (Phoenix, AZ). It's a collection of friends that experienced the old days of the Hand in Hand Christan evangelistic ministry in the late 70's. Terry and I were both in bands back then. There are some pretty funny pics there.
Our friend, Bernie Rolfe has also created a website with lots of history and even quite a few recordings from that season of life. There are photos there too.
Terry's band was Glory Road, and the band I was in was called Shira.
