It is not exactly the businest week of the musical year, but there isone current event that would be special at any time. On WEdnesday, the Summer Operat Theater Company is producing Leos Janacek's intense, searing opera tale of adultery and suicide, "Katya Kabanova," which he introduced in 1921. It is the first of the great works of Janacek's remarkable final period, when most of his greeatest music was written, after he started an adulterousrelationship with a woman almost 40 year younger than he was. Performed at Catholic University's Hartke Theater, "Katya" will be repeated Friday and next Sunday.

For anyone who came of age during the 1960s, "Beehive" (at Arena's Kreeger Theater) strikes all the right chords. Here, recaptured by a talented cast of six, are the female vocalists and girl groups that presided over the decade. If you wept with Lesley Gore, were inflamed by Tina Turner, felt for Connie Francis or drooled over the Supremes, you'll be right at htome. The show, which takes its name from the towering hairdo that enjoyed a brief vogue back then, is also a living catalogue of delierious fashions and syncopated dances.Did we really carry on like that? Apparently, we did.
