The soundtrack to a 1972 TV special, Liza with a "Z" was by far her most popular album, reaching the Top Twenty of the charts.Inevitably, much of the impact of a program by a performer such as Liza Minnelli is lost in an audio-only document, and some fansmight prefer the DVD of the special for that reason. As you'd expect, the musical selections for the program showcase herversatility, including standards such as "Bye Bye Blackbird" and "My Mammy," as well asBillie Holiday's "God Bless the Child" andCharles Aznavour's "You've Let Yourself Go." Perhaps to prove she was keeping up with at least some trends in contemporary music, there are alsocovers of "Son of a Preacher Man" and (as even more of a stretch)Joe Tex's "I Gotcha," though she's not going to make anyone forgeDusty SpringfieldorAretha Franklinwhen it comes to this kind of material. Of course, she was far more at home with show tune fare and, as expected, it's the tenminute "Cabaret Medley" that goes over best.
