It's been quite a comeback for Garth Brooks. Even the most imaginative fan couldn't have guessed the legend's return to the spotlight would include digital music, a satellite radio channel, five million tickets sold and ... well, it's just beginning.

These six unforgettable moments from Brooks' first two years of touring include plenty of tears — and quite a few cheers. Trisha Yearwood makes two appearances, and Justin Timberlake somehow sneaks in there. But the most unforgettable things that happened involve fans and Brooks' own spontaneous reactions.

One young man brought him a gift, while an older female fan surprised the singer with a sign that nearly knocked him on the seat of his pants. Watch as Brooks interacts with his crowd as honestly and effortlessly as he does other country and pop stars — hey, he's not selling out multiple shows at each venue for no reason. The Entertainer of the Year nominee has one of the best live shows in country music, and he says his days as a retiree are behind him.
