That video from Wellspring Family Services features West Seattle-residing rocker Chris Ballew, who in his Caspar Babypants kindie-rock mode is once again offering a once-in-a-lifetime prize as part of a fundraising contest that has two weeks to go. It’s the annual “Kids Helping Kids” coin-collecting drive. Wellspring helps homeless kids and families around King County; everybody who turns in donations via “Kids Helping Kids” gets entered in the drawing for Caspar B to write a custom song about them. (In the video, you’ll hear part of “Happy Heart,” inspired by 7-year-old Rena Mateja, who collected more than $500 for Wellspring.) Deadline is September 1st; donations can be turned in to Wellspring directly or via CoinStar machines. Information on how to sign up and how to donate is in the links on the right sidebar of this page.
