He's certainly still got it. Garth Brooks' first 20 concerts at the Wynn Las Vegas Encore Theater sold out in just five hours. The Wynn's website and phone lines were jammed on Saturday -- the day tickets went on sale for the first leg of the country superstar's Sin City run. After answering 141,934 calls, the resort's phone system reached maximum capacity and callers started receiving a busy signal. The Wynn website got 5.4 million hits in just 24 hours.

Garth announced earlier this month that he is coming out of retirement to perform in Las Vegas for 15 weekends per year, for the next five years. The shows from this December through February are now sold out, but future dates will be announced soon.
