Ok, I used to have this on tape. The sound quality was lousy. It sounded more like a good bootleg, rather than a high quality live album. I have not heard this version, yet. I will say one thing, this is a classic concert. The original line-up with a good song selection. The musicianship is right on, although Ozzy is quite pitchy. When is Ozzy NOT pitchy. LOL. I would say that it worth a listen, but $23.00 is a bit pricey for a concert from ‘72.
