OUT AND ABOUT. According to the people at Nightstage, Ronnie Laws cancelled his show at the Cambridge club last night after hurting an arm in an accident . . . See Edna? Just like in the movies. After two years of struggling financially due to lack of sponsorship, this year's Greenwich Village Jazz Festival in New York was just about to be cancelled (notices were ready to go out) when Hennessy Cognac came to the rescue. Now the event is on again, scheduled for August 26-September 5 . . . The Library of Congress just announced that "a large number of manuscripts of Jerome Kern's music has been deposited at the library and will be available to the public for research purposes." The material includes tiles such as "Show Boat," and "Very Good Eddie" as well as unpublished manuscripts . . . I've never been a purist but -- the Georgia Satellites at this year's Montreux Jazz Festival? . . . In the past few months there's been a flood of releases of Brazilian music, and more is on the way. CBS joins the crowd with releases by singers Djavan, Milton Nascimento and Simone, a terrific vocalist very popular in Brazil but unknown in the United States . . . Speaking about Brazilian music: The Manhattan Transfer, which performs tonight at Great Woods, recently released "Brazil," an album that includes covers of Nascimento and Djavan's songs. Their press agents modestly claim that "it took a group with the stature of Manhattan Transfer to turn America on to the sound of modern Brazil." Puhleeze. Gentlemen, this may be serious. Have a seat, loosen your collar and stay away from the typewriter. Besides, "Brazil," which sounds like mall music done by well-meaning-but-confused gringo tourists, takes contemporary Brazilian music back 20 years.
