My older brother always called Grand Funk his favorite band but would never buy any of the albums. He insisted they were a different band live.
I have to say this is a pretty relentlessly rocking show. Yeah sure it's old and there's an element of looking back at the 70's that has a very "Spinal Tap" feel. But damn they rock.
