Saw them live right here in Ruston, LA in 1976. Louisiana Tech.

I was at the show in New Orleans the previous night, at The Warehouse. When I saw the tickets for a Dallas show go on sale last November, I grabbed them without hesitation. The August 13th show was like a time-warp back to the '70s... and it had one of the most enthusiastic audiences I've seen at a concert in years.
