Listened to a soundboard yesterday of their 15/01/73 gig - magnificent. Today, I listened to a soundboard of their final rehearsal (it says) before their O2 gig in December 2007 - again magnificent. There will always be glass half empty whingers complaining about their material - the fact is that they performed with an energy never shown by some toothless USAian blues singer who may have invented the original song!!!
