Below is a link to one of the best pieces of sound engineering work I think I have ever seen.  It is a composite audio/video of song whereby additional tracks were laid in by different singers and musicians from different places around the world.  The finished product is tremendous!

The song itself is that classic standard "Stand By Me" originally released in 1955 by The Staple Singers and released again in 1961 by the Drifters..

This composite version is a real toe tapper, so turn up the speaker volume and

 Footnote:  Washboard Chaz was a regular on the Boulder scene in the 70's.
