I'm with Paul on this one they should play Knebworth 2009, the 30th anniversary is next year so a gig at Knebworth would be an excellent way to celebrate.
Just trawled thru this thread and one name is missing The late great Rory Gallagher, he like Jimmy could play rock, blues and was a mean acoustic player too. I'm not saying he was better than Jimmy but he was up there with the best!!
