* * “ONE VOICE,” Barbra Streisand, Columbia. The performance that led to this album is billed as Streisand’s first full-length concert in 20 years. But there’s a big difference between the two shows. Streisand’s last full-length concert was in front of 135,000 fans at New York’s Central Park. This one was last year in front of 500 friends and associates in her backyard in Malibu. The show--a benefit for anti-nuclear, environmental, civil liberties and human rights groups--aired as a cable TV special and is also available on videocassette.

We know what you’re thinking: “I like Barbra Streisand, but I already have a lot of her albums. Isn’t this mostly just live versions of songs I already have? Do I really need to pick this one up too?”

That all depends. If you’re a fan, by all means get it. The highlights include superb versions of two songs Streisand had never recorded before--”Over the Rainbow” and “America the Beautiful”--and interesting new takes on two songs she had cut. Streisand gives “Happy Days Are Here Again” a hopeful, optimistic reading instead of the downbeat, cynical interpretation that made it her first signature song. And she and Barry Gibb give “Guilty” a harder edge than their hit duet, turning it into a tough, sexy hustle.

If you’re not that big a fan, you may find yourself nitpicking. “Isn’t ‘What Kind of Fool’ a pretty mediocre song to include on a collection like this?” (Yes). “Isn’t Streisand over-singing on the second half of ‘People’?” (Yes). “Wouldn’t it have been better if the concert had been open to the general public and not just a hand-picked gathering of rich and powerful Hollywood types?” (Yes). “Shouldn’t Streisand deign to give a full-length concert more often than once every 20 years?” (Definitely yes).
