Eric Clapton already announced four US shows -- two at NYC's Madison Square Garden, two at LA's Forum - that might be part of his last tour ever. "I swear this is it, no more…..I know I’ve been threatening retirement for the last fifty years," he said.

Available tickets are running low for those shows, but now Clapton added two more at each venue. He'll play September 7 & 8 at MSG and September 15 & 16 at The Forum. Tickets for the newly-added shows go on sale Saturday (2/4) at 10 AM with Chase/fan club presales starting Thursday (2/2) at 11 AM and noon.

Like at the March shows, Gary Clark, Jr. and Jimmie Vaughan will be guests. Clapton says he isn't adding anymore US shows in 2017 after this.
