"Playing For Change" is back with another amazing world-wide cover

(CBS) - About two weeks ago we introduced you to the international music collective "Playing For Change" doing an amazing world-wide cover of the Rolling Stones' "Gimme Shelter".

Well, they're back with another mind-blowing, location-jumping video above that you need to check out.

This time the cover is of the Otis Redding timeless classic "Sittin' On The Dock Of The Bay". They write about the video:

Today our heroes and soul brothers, Roger Ridley and Grandpa Elliott, return for a new song around the world, "Sitting on the dock of the bay", featured on our new PFC 2 album. I once asked Roger why with such a powerful voice like his he was singing on the streets, he replied, "I am in the joy business, I come out here to be with the people"

A beautiful sentiment and I am once again blown away by this amazing organization's cover - to learn more about the project, you can go to their website HERE.
