I've got a mountain of V.U. bootlegs, all of various quality. This one, maybe the most well known one too, is still one of the best in terms of sound quality and content. The debut of Sister Ray is definitely a selling point, as is the inclusion of I'm not a Young Man Anymore (sounds like something I'd write). If you don't have this already, it's a no brainer. But I'm guessing someone with as fine taste as yours already has a copy of this.
