We'd heard a lot in recent weeks about just how crazed Liza Minnelli has been in recent media appearances, while out promoting the DVD of her 1972 TV special, "Liza With a Z." Come on, we thought, how shocking could they be, after all we've read through the years? After this? Alas, we were surprised -- but yes, we were surprised. The first is an appearance on "Larry King Live" expertly edited down to its essence here, the second is a recent appearance on "The Ellen DeGeneres Show," and the last is a legendary (you'll see) 2004 appearance in "The Royal Variety Performance."
