It was used as the title song for Blues Brothers 2000, I can't remember who did it, but a fantastic version anyway. It's also used in the film with the full Blues Brothers band, and gospel chior.

I know the plot isn't the best, but the music and performers read like a whos who of the blues and soul world! And as for the jam session at the end....................Man you could sell tickets for that for millions!

Wassail!! Chris.
