Charlie Musselwhite’s - Slow Blues (cover)

I was really astounded, when I first listened this song played by Charlie Musselwhite & Richard Bargel. Here you can find the inspiring video: Another version of the tune (performed in ’rough’ Chicago blues stile) can be found , on Charlie Musselwhite’s album Delta hardware released in 2006 named Just a feeling. The song was originaly performed by blues legend - Little Walter.
