It's been several months since the folks at One Degree Events have put on one of their notoriously well-organized flash mobs, but I just received an email that a Glee Flash Mob is happening on Saturday at three to-be-revealed locations.

If you're not familiar with a flash mob, it's essentially an impromptu dance party, usually in the middle of a crowd or on a busy street, that appears to happen out of nowhere but is actually planned and highly choreographed. The most recent local flash mob happened last August , when several hundred dancers celebrated the music of Michael Jackson by doing all of the syncopated dance moves in "Beat It" on the streets of Pioneer Square, Park Place Market, and at Kerry Park.

This time around, organizers Bobby Bonsey and Egan Orion are focusing on music from "Glee," the popular FOX show about a high-school glee clubs, which starts its second season next Tuesday. On Saturday, you can expect to see dancers in the streets of Seattle to a mix of "Don't Stop Believin'," "Proud Mary," "Gold Digger," and "Somebody to Love." That's a tough mixture, and people have been practicing for months to get ready. Bonsey recently recorded a set of instructional videos to help people practice at home.[youtube]http://www.youtube.com/watch?v=FO1Frx5gJ84&feature=player_embedded#[/youtube]

There's one final group practice session this Friday from 6 pm to 8 pm at the Century Ballroom  (915 East Pine St.) before everyone meets up Saturday in Cal Anderson Park at 10 am.
