I always have thought Heaven & Hot Rods is one of the bands best tracks. That song has so much drive and power to it, it would be killer live. Church On Tuesday...although its a great song, I consider it something that sounds great on the album, but wouldn't work as well in a live setting as it does on the cd.
If they opened their set up with Down, went right into Heaven & Hot Rods, and then played Vasoline...that would be perfect. I think It would get the crowd movin, big time.
