Remember that music you used to listen to before you had kids? That rockin', funky stuff that made you jump to your feet and shake your groove thang? If too many renditions of "Twinkle, Twinkle Little Star" have left you feeling over-the-hill, check out Peanut Butter and JAM, the second CD by San Francisco music teacher Charity Kahn. The tunes - ranging from silly to serious to seriously funky - will make you feel cool again, and your kids will love them.

A classically trained pianist, flutist and vocalist who holds a degree in math from Stanford, Kahn sings and plays spirited songs bursting with creativity and originality. A mother of two, she approaches music as a celebration.

"I want to get families to bond, lose their inhibitions, lose the stresses of the day and just feel real and alive," says Kahn, whose husband Charlie plays bass on the CD and at her gigs.

On Peanut Butter and JAM, Kahn shows her virtuosity in genres as varied as surfer music, jazz, country and even lullabies. The songs are geared for young audiences, but the lyrics and instrumentation satisfy sophisticated tastes, too. And Kahn's band makes the whole thing feel like a party.

Peanut Butter and JAM is $15 and available at www.cdbaby.com/jamband and at Kids Only on Haight Street, Day One Center in Laurel Village and The Ark on 24th Street.
