Eclectic. That's the adjective to describe the type of people who frequent Starlite Diner, and to describe the perfect crowd for this fad that will not die. There's "Roxy," age fifteen. Hidden inside the Kendall Village Plaza, under the mask of night, she and some of her fellow Narcotics Anonymous group members are huddled, pounding cheap drinks and perusing the long list of songs. On the stage, four gay frat boys eat it up as the large audience goes crazy over their performance. (Suggested name for this group should it seek stardom: The Four Gay Frat Boys.) In the bathroom -- beyond the Fifties-style décor that reminds one of a more innocent time -- a waiter from the restaurant across the way is being arrested (bench warrant). He was holed up in a stall with two girls snorting coke. An angry boyfriend of one of the girls has called the cops, and in a few moments they're taking Powder Nose away in cuffs -- just as Karaoke Ben, the emcee, is calling for the jailbird to perform a rendition of Vanilla Ice's "Ice Ice Baby." Now that's karaoke.
