Summer is almost here and after becoming a more scarce sight in recent years it's nice to see that the infamous "ROCKABILLY DANCERS" of Tokyo's YOYOGI OLYMPIC PARK  are back in full effect. Convening in the park as a weekly Sunday ritual, for years these cartoon rockabilly heroes have set up camp in full gear complete with a throng of period-attired betties, custom cars, and a portable sound system pumping out high-octane vintage rockabilly to power their day-long Sha-Na-Na-worthy dance performances. Needless to say, it's a sight that must be witnessed in person to be believed. HAVE A LOOK:
