Alison Krauss, Shawn Colvin and Jerry Douglas - ‘The Boxer’ [Paul Simon]

 and finally this . . . . . . 

"On May 23rd, 2007, I performed at a concert honouring Paul Simon in celebration of his winning the Library of Congress Gershwin Prize. 

Alison Krauss and I performed “The Boxer”, featuring Jerry Douglas. What incredibly amazing company to be in. The best of the best. Paul came into our dressing room while Alison and I were rehearsing. He seemed to approve of what we were doing. Phew!” Shawn Colvin
