An almost-last-minute addition to the lineup for Saturday’s gala celebration of the Delridge Playfield renovations – Seattle Parks confirmed late today that six drummers from the acclaimed Chief Sealth International High School Drum Line will perform as part of the festivities, right before the speeches. That means they’ll be on between 1 and 1:15 pm. (Our video above shows the drum line performing at the Tacoma Dome last week while the Sealth boys were in the state tournament.) The West Seattle Soccer Club is co-sponsoring the celebration with DiscNW; there’ll be disc games as it starts at 12:30, and soccer games after acting Parks Superintendent Christopher Williams and City Councilmember Tom Rasmussen lead the formal dedication around 1:15. As planned during the design meetings we covered back in xxx, the field now has playing zones for soccer, baseball, softball, disc sports, and lacrosse (which was added to the plan by request during the community meetings we covered a year and a half ago). Its new lights use a third less electricity than the old ones, according to the city. The $3 million-plus project was paid for by the Parks and Green Spaces Levy, approved by voters in 2008.
