DOCTOR NIGHTLIFE is still off nursing a black eye. She sent in a few notes, though -- signed "Nadine." Now all she needs is a cup of coffee and a doughnut. Meanwhile: FRIDAY

BACK TO BLACK --

The Friday night dance "season" returns to the Kennedy-Warren ballroom, with the KW Orchestra performing from 9 till midnight; admission $8, and '30s and '40s dress always welcome. Meanwhile, you have just two more chances, tonight and Sept. 28, to tango for free outdoors at the Bethesda Metro Plaza, with the Richard Bray Orchestra, 6 to 9 both nights. We think you should dress for excess. On Saturdays starting Sept. 29, incidentally, the Kennedy-Warren also hosts the "Kabarett Washington," a pre-war German/French-style dinner cabaret, in the North Lounge. "Cabaret" is interpreted widely -- jazz, Broadway, Brecht, bouffe. The 8 o'clock show includes dinner, $23; the show at 10 is cash bar only, $8; call 483-2058.

AFTER MIDNIGHT --

Midnight Oil has been burning its own midnight oil lately. They're back in Washington for the second time this year, indoors this go-round at GWU's Smith Center with the Origin ($19, 432-0200).

SUNDAY

WEISS GUYS --

Michael Weiss, second-place finisher in the 1989 Thelonious Monk International Jazz Competition and currently a member of the Johnny Griffin Quartet (he was last seen at Blues Alley with Art Farmer), performs a special "Tribute to Bop" featuring the music of Monk, J. J. Johnson, Joe Zawanoli and Weiss himself at the Museum of Natural History's Baird Auditorium ($16; 357-3030). Weiss is sided by bassist Peter Washington and drummer Lewis Nash.

MONDAY

BUSH LEAGUE HUMOR --

It's hard to miss taking potshots at the political situation, but we think the logical double bill for some forthcoming comedy club is the Pheromones and Gross National Product. The Pheromones have succumbed to parody with a medley of "Jailhouse Iraq" and "Hussein's Hotel" (see them at the House of Musical Traditions' Monday night concert at the Silver Spring Unitarian Church; $6, 270-9090); and GNP has got its "Bush of Arabia" shtick down pat at its regular Bayou Saturday night. Next we predict an 18-hole game called gulf -- all sand traps and no Kuwait in line.

TUESDAY

DROP-DEAD HUMOR --

Now that he's writing detective stories, some clever PR firm is bound to chortle that songwriter-comedian-author-poet Steve Allen is getting away with murder. For money. But just wait'll they hear those awful Somerset House ads (through Sunday at Anton's 1201 Club; $29.50, 783-1201).

THURSDAY

RE-FOLKUSSED --

Ellicott City's nonprofit and see-worthy Folkal Point reopens for the fall season with a special Dick Cerri "Music Americana" showcase to benefit the World Folk Music Association, featuring Pete Kennedy, Side by Side, Dodie MacMillan (with banjoist Mike Munford and mandolinist Dave Giegerich) and the Back Seat Drivers. Admission is $5; the Folkal Point is upstairs at the Cacao Lane restaurant, 8066 Main Street; 301/982-0686.
