The flute on "With You There to Help Me" knocks me out!
And Locomotive Breath still makes me go 20 over the speed limit.
Have you heard Divinities? His flute playing is just incredible. One of my favorites is the live album "A little light music", the rendition of Rocks on the Road is riveting and the 5 mile acoustic intro by Martin on Too Old to Rock and Roll would shame many guitar players that people think of as great.
