DOCTOR NIGHTLIFE has resolved to spend the holidays in search of inner peace and universal harmony, and in pursuit of same was seen streaking southward in a hot black car. Leave encouraging phone messages. And let 1991 be 1991. Until then: FRIDAY

FAMILY AFFAIR --

The Kelley brothers, a k a Frontier Theory, re-play their now famous three-hour all-acoustic (all-you-can-beat) Armand's special at d.c. space ($5; 202/347-1445), a spicy mix of old and new originals and fun covers.

SWING DING --

Hate auld lange syne? LaMar Carlson and his Rock 'n' Roll Swing Band work it out '50s style at Synergy ($7, with workshop $12; 202/363-4664). SATURDAY

FAMILY AFFAIR, 2 --

Music Americana's seventh anniversary showcase features Washington's own Smith Sisters, the Shaw Brothers (who before going sibling-solo were members of the Brandywine Singers and the Hillsiders), guitar-throb Pete Kennedy and regulars Side by Side, at the Birchmere ($10 benefits the World Folk Music Association; 703/549-5919). Intimate sources say that when the Smiths and Shaws join forces, they sound like dead ringers for the Weavers. SUNDAY

BECAUSE, BE CAUSE, WE LIKE YOU --

The New Year's Eve Eve (we had nothing to do with this) bash at Baltimore's 8X10, featuring the slinkily infectious Mambo Combo, is -- even better -- a benefit for the House of Ruth women's and children's shelter in Baltimore. Like Washington's House, it provides counseling, legal aid and education as well as shelter ($5; 301/625-2000). Black tie is optional, but charity never goes out of fashion. MONDAY

NEW YEAR'S NIGHTSHIFT --

The Nighthawks are a longtime Washington New Year's Eve tradition -- only now that the Bayou has become the home base for New Potato Caboose ($15.50; 202/333-2897), and Twist & Shout is MIA, the Nighthawks are cooking at the Hard Rock Cafe ($30; 202/737-7625 or 202/432-0200). Twist & Shout's other holiday tradition, Tom Principato, is out at the Broad Street Seafood and Barbeque (nee Champions) in Falls Church ($20 including champagne, or $85 per couple for dinner; 703/536-4386). You need a menu to keep track of the players.

NO PASSING FADD --

We knew it was coming. MADD, SADD, BADD (which the Doctor predicted, you recall) -- and now FADD, Folk Against Drinking & Driving. It's a no-spirits, no-smoking New Year's Eve showcase at Folk Alley (in the Washington Ethical Society, 7750 16th St. NW; admission $8). The all-area roster includes Vicki Pratt Keating, Jane Gillman, Side by Side, Sue Trainor, Jimmy Landry, Terra Nova, Wellspring, Rebecca Becraft, Lou Fournier, Frank Johnson and Steve Key. One Side Doris Justis is in charge; ask her (202/686-9210).

PIONEERING WOMAN --

The original queens of country music weren't sweet-voiced; the matriarchs like Kitty Wells and Mother Maybelle Carter had the rough, forceful projection of a pioneer farmer and the rigid back of the true believer. Virginia Veatch is an unabashed descendant of the non-quavery kind; and her writing follows as close to the furrow as a plow. Virginia & the Bluedots kick off the new year with New York's skidmark-garage rock-bomp A-Bones at d.c. space ($10; 202/347-1445).
