No harp, but I was listening to this and couldn't think of any other place to post it to where someone might appreciate it.
I couldd listen to this groove all day, and inadvertently have (you know that thing where you hear a track playing in your head and you just can't get it out).
Mark has created some hellatious grooves ... in Dire Straits and his solo works...check out "Calling Elvis" for one.... One of my favorite non-harmonica musicians.
