If you're looking to hear "Grandma Got Run Over by a Reindeer," forget it. But if you're hoping to get into the spirit of the season the old-fashioned way, march on down to the Kennedy Center Concert Hall this Saturday for a potpourri of musical and cultural events sure to put a glow on your cheeks.

At 2, the Chevy Chase Elementary School Chorus teams up with the Paul Hill Chorale for a two-hour concert of traditional Christmas tunes, Appalachian folk songs, seasonal music from Old Europe and songs of Hanukah, with storyteller Chip Brienza providing narration for the children. The affair opens and closes with a candlelight procession and there'll also be pre-show caroling. Tickets range from $5 to $17.

Afterward, concertgoers will be met in the Grand Foyer by ten handbell choirs that will provide a ringing touch to the holiday. Free musical events continue into the evening in the Kennedy Center foyer with the Nevilla Ottley Singers and Flamenco Fiesta.

Then, at 7:30, the Shir Chadash Chorale performs in a traditional Hanukah festival in the Concert Hall, with more than 21/2 hours of Yiddish folksongs, Hassidic music and excerpts from Handel's "Judas Maccabaeus." The festival also has area children's choirs, dancers and the lighting of Hanukah candles. Tickets are $6. For tickets to this or the Paul Hill Chorale, call Instant- Charge, 857-0900.
