Amsterdam based DJ Oscar is a regular contributor to Christmas A Go Go. You can see him live, spinning Xmas records at various occasions:
dec 21 Paradiso, Amsterdam (with Mischief)
dec 23 Concerto Recordstore Amsterdam (with The Sleigh Shakers)

One of the singles he'll certainly play is the one from the High Five Four, a nice rockabilly tune from Amsterdam.
