I bought a copy of this a couple of years ago, but it was defective and I had to return it. luckily I bought it at a "brick and mortar" store. I bought this one and it works, then my sister watched it and had issues with it! no I say! deja vu all up in your face. luckily it is the first track of the concert (the night concert, which is the reason to buy this). the first track merely shows people showing up for the show and aside from being a great time capsule of seeing bolan fans in the period, not essential. alas, the rest plays perfectly and that's that. for anyone really curious about this, you're probably already a big enough t. rex fan that you'll get it anyway. it is WELL WORTH THE MONEY. and the value has not gone down since I bought the copy I returned like 6 years ago, which shows that it is a quality item that is still holding it's own, whatever that means.
