Sorry, but these didn't sound "old" to me! I must be really old to you, 59. Course, when I was younger, I didn't listen to Christian rock. My favorite group was Chicago or Credence Clearwater. No offense intended.
I remember on a trip with a college group to Hutchinson KS seeing them at a local college there. (Met a lot of Mennonites there.)
Anyway since I was asked to go since we were promoting concerts at the church we were going to, I was just hanging out at a cafeteria area there and lone behold Scott Wenzel (the lead singer) just came down to get something to eat and we hung out for a couple of hours. (He had a cold and wasn't feeling well, a number of us prayed for him and off and singing he went like nothing was wrong.)
