Turning 60 doesn't seem to be slowing Elton John down much... he's doing a stand of dozens of show in Las Vegas, and is also playing concerts at various places in the U.S. and elsewhere (including Europe and New Zealand). A few years back he signed a deal to perform 75 concerts at The Colosseum at Caesars Palace in Las Vegas. This show, called "The Red Piano," isn't just an Elton John concert but (fitting for Las Vegas) but a show that "present[s] Elton’s great songs in a musical and visual extravaganza."
Elton John is also doing a series of more traditional concerts with his band in places like Paris and Vienna, but also some smaller towns that might seem unusual choices for an Elton John show: Darlington and Doncaster in England, and in the U.S. the Beasley Performing Arts Coliseum at Washington State University in Pullman, and the Adams Center in Missoula, Montana.
Tickets for the Beasley and Adams Center shows seem to be sold out through their ticket outlet, Tickets West (www.ticketswest.com), but you might be able to buy Elton John tickets through StubHub or other ticket brokers. The Elton John Web site also notes that more shows will be added, so you might want to check back with the official Elton John concert page at his site.
I've liked the music of Elton John since I first heard "Rocket Man" from his Honky Chateau album in 1972 (yeah, I'm that old), and I never would have guessed back then that this flamboyant superstar would still be rocking into the 21st century. Of course, back then, I thought that anyone over 30 was really, really old...
