From their holiday concert at Grace Church on Thursday night, it’s a hi-def West Seattle Big Band Christmas medley – 6 minutes packed with swingin’ sections of multiple holiday faves. (In the mood for more music of the season? Tomorrow’s the Fauntleroy Church [WSB sponsor] Christmas concert, 6 o’clock – one of many holiday events on the West Seattle Holidays page, which now stretches to New Year’s Eve/Day.)
