How about a little show clip from a concert I was fortunate enough to attend? It started with the last public performance by Tears for Fears in the rain at about Noon. Midway through, Elton joined up with Clapton, and a few songs later ... Mark Knopfler. And, oh yeah, later on? Genesis Reunion - w Rutherford-Banks and Collins, then Page and Plant. McCartney and then Pink Floyd in a glorious finale. I'm forgetting a few. Twelve hours, plus of rock.
(Please note the way Clapton just backs Knopfler up...)
