Prior to his opening night Friday at Wynn Las Vegas' Encore Theater, Garth Brooks revealed in a press conference that he plans to launch a world tour in 2014, complete with full stage show, band and lighting. (At that point, his youngest daughter, Allie, will be out of high school.) According to USA Today, before Garth even sang one song at his second show Friday, a man yelled, "Thanks for coming back!" Brooks responded, "Are you kidding me? Dude, this is awesome!" Garth, who acknowledged that he felt like the audience was in his living room, accompanied himself on acoustic guitar. Wearing a hoodie, jeans and a Garth Brooks World Tour ball cap, he took requests and answered questions from the audience. Brooks told the crowd, "I don't know about you, but I can promise you none of you are as excited as me." Although Garth was a little rusty after nine years of retirement, the audience gave him a standing ovation for a part a cappella version of Billy Joel's "Shameless." Just as Brooks had hoped for when he announced the concept for his Vegas shows, the set lists were very different Saturday night. According to Entertainment Weekly, though, "Shameless" once again brought the house to its feet. Garth quipped, "Revelations are what life’s all about, and I just had one: What the hell am I paying the band for?" When the audience took over singing some tunes like "Rodeo," he commented, " This might be the easiest gig of my life!"
