In conjunction with Phish’s performance of Little Feat’s Waiting for Columbus on Halloween, the Mockingbird Foundation is offering a free download of Little Feat’s version of Phish’s “Sample in a Jar.” The song was recorded for Mockingbird’s double-disc tribute album Sharin’ in the Groove. The rest of the album is available for purchase, with the process set to benefit music education for children. The download link can be found here.
