"Good to Go," the much ballyhooed and oft-delayed film inspired by Washington's one-time secret, go-go music, will get its world premiere July 31 at the Warner Theatre. The screening, a benefit for the antidrug organization RAP Inc., will be followed by a concert by one of the film's featured bands, Trouble Funk.

"Good to Go" was originally scheduled to open in August 1984 but a number of production problems kept it from opening then, when it would have been the beneficiary of a worldwide media blitz on go-go music. The sound track from the film, featuring cuts by Trouble Funk, Hot, Cold Sweat, EU, Chuck Brown and the Soul Searchers, and Redds and the Boys, was released a few weeks ago by Island Records. The film was produced by Island's Chris Blackwell, whose championings of reggae on record and in his film "The Harder They Come" are seen as models for breaking go-go out of Washington. The Angry 'Word'

The Junkyard Band's new Def Jam single, "The Word," is the most politically pointed song to emerge from the go-go scene since Chuck Brown's "Money." The rhythmically propulsive tune probably has more mentions and repetitions of the name Reagan than any single in the last few years. Produced by Rick Rubin, it sets up several different scenes -- a welfare mother applying for food stamps, a farmer and a student trying to get loans, people being moved off their land for an Air Force base -- and connects them with a common thread: Their government aid has been cut back because "Reagan gave the Pentagon all the people's money." Dear Jurisprudence

The arraignment of Jello Biafra, lead singer for California's Dead Kennedys, on charges of distribution of materials harmful to minors (the band enclosed a sexually explicit poster by Swiss artist H.R. Giger inside its latest album, "Frankenchrist"), has been rescheduled for July 30 after the American Civil Liberties Union stepped in as one of the counsels in the case. ACLU lawyer Carol Sobel, who will work with Biafra and four codefendants, maintains that the case involves vital First Amendment rights and that the statute invoked has been misapplied.

Also in California, five major record companies have asked that a suit by independent promoter Joe Isgro be dismissed, claiming his antitrust action against them offers inadequate grounds for litigation. Isgro is seeking $25 million in damages because several major labels terminated his services after a February NBC News report alleged that Isgro had links with organized crime; subsequent to those reports, major labels severed their ties with independent promoters.

RCA and Arista (with A&M, Capitol, Chrysalis and MCA filing "joinder" motions) argue that Isgro's complaint has no factual basis for its charges of federal and state antitrust violations. Other companies named in the suit, including Polygram and the Warner-Elektra-Atlantic labels, have filed answers to the suit; the defendants' motions are scheduled to be heard Aug. 11. MTV or Not TV

It wasn't exactly "Gone With the Wind," but Quiet Riot's new video, "The Wild and the Young," received its world premiere on MTV 10 days ago, and in subsequent showings, some people -- including the band and CBS Records -- noticed that MTV had done some quick editing. The clip, directed by Jeff Stein, is a satire on rock censorship and fundamenta-moralists in which the band is caught in an Orwellian police state where rock musicians are herded into detention camps and their instruments flung into shredding machines. Escaping the Brain Police by scrambling down a manhole marked "High Voltage," Quiet Riot incites a not-so-quiet riot among the other prisoners by playing "The Wild and the Young," until the Brain Police surround the band, guns poised.

At this point, lead singer Kevin DuBrow wakes up on the band's tour bus and finds out it has been just another bad dream. But then a newscaster (Wink Martindale, of all people) announces "In Washington, Congress has just passed legislation that requires record companies to reproduce song lyrics on all album jackets. Warning stickers must be fixed to alert parents to explicit subject matter. The government has cited the rock and roll band Quiet Riot as one of the chief offenders . . . " At which point the bus driver turns out to be one of the Brain Police and the tour bus pulls into the detention center.

So far so good (although Quiet Riot was not actually cited in the Parents Music Resource Center hearings that dealt with explicit lyrics on Capitol Hill last year). But MTV, which has had a number of discussions with PMRC about its programming in the past, started running a sanitized clip, ending it when DuBrow wakes up and axing the newscast and denouement. MTV insists that the editing was done to fit tight time slots and that it often edits extraneous dialogue (though not, unfortunately, by its veejays). After CBS and Quiet Riot lodged protests, MTV agreed to run the clip uncut.
