[purchase link - free Creative Commons download at archive.org]
Here's a 4-5 year old version of a song originally recorded by Sly and the Family Stone back in '69. The band performing this version is My Morning Jacket and it's a live version from (once again) the Creative Commons servers at archive.org.
This is just one of about 20 songs from what appears to have been a legendary set from this band out of Kentucky (you can check out the rest of the set via the "purchase" link above).
