The recent death of Johnny Winter last week really got me to thinking of a few other greats I wanted to see one last time before they die. A recent search on the web yielded that John Mayall is going to be in Walnut Creek, CA this next Friday July 25th so I already bought tickets. My advice is to go see these guys before they are gone forever. Mayall is older than God (81 this November) so this may be the last time/chance you ever get. http://www.johnmayall.com/tour.html .
