Best Live Albums Ever

IIRC, wasn't Speak of the Devil quickly recorded in NY at the Ritz as apart of some deal Ozzy made with old Black Sabbath manager and -current father and father-in-law Don Alden that ended their partnership? (I've heard Don Alden never was really fond of Ozzy's musical abilities as far back as mid-70's after becoming Sabbath's manager after endless lawsuits from former management groups and I've heard rumors Alden was connected to some pretty shady London underworld types like Kray Brothers, and NY's Gambino crime family in the 60's like when he threatened Robert Stigwood, Cream's manager, by dangling him from a 4-story building for trying to lure Small Faces away from one of his labels.

I hate to be a year and half late mentioning this, but original Live at Leeds didn't include any songs from Tommy, other then Townshend introducing songs like A Quick One While He's Away as "Tommy's Parents" and maybe Sparks. The band,by then had grown tired of touring Tommy for over a year and wanted to showcase songs they hadn't played live for years and were as completely separate from Tommy because Townsend's concepts were getting bigger, deeper and more complex philosophically as he began toying with enormous multi-media concept Lifehouse that he labeled "Brave New World in rock terms"---a future dystopian society where people live in collective communities called "Grids" wore plastic lifesuits and were force-fed music and entertainment intravenously similar to massive Matrix-hard drive except for scattered few who lived outside grid range, including a farmer-***-roadie named Bobby, who discovers outlawed rock music can be heard at a place called the "Lifehouse". Townshend's ultimate aim in Lifehouse was to say that whatever happens, rock n' roll will save the world.
