I've been playing a heavy rotation of live Dead CDs lately and it got me figuring. I have around 100 live albums alone in my music collection (official releases and bootlegs). Most live albums do have an overdub or two (or in the case of Waiting for Columbus 50 or so) but there some that are completely live with no overdubs. My favorite album of all time, It's Too Late to Stop Now by Van Morrison is one of these. So is Dire Straits Alchemy album.

By the way Bornyo, Robert Plant and Jimmy Page laugh at your idea that teenage girls weren't losing control of their bladders at Zeppelin shows. For proof listen to the lyrics of Sick Again. Between that song, Stray Cat Blues, and Cypress Avenue to name just a few I have to think that the age of consent in Great Britian in the late 60s was about 12.
