They’ve been practicing for weeks (see video of their latest dress rehearsal here) – and now it’s almost showtime for the Thrill the World/West Seattle crew, joining forces with the citywide group in the collective attempt to help set a world record this Saturday for dancing to the Michael Jackson classic “Thriller.” Tonight they have one last rehearsal, and then organizer Lora Lewis from Hotwire Coffee (WSB sponsor) says they’ve gotten final approval for the official on-the-record-for-the-record dance to be in Pioneer Square’s Occidental Park at 11 am Saturday – then you have two chances to see them in West Seattle: 2 pm at Easy Street in The Junction, 9 pm at the Admiral Theater. (This is all in the Halloween section of the WSB Holidays page, too.)
