ARLINGTON, Texas — Known for his easygoing manner and everyman’s appeal, country music legend George Strait strolled from the floor of the Dallas Cowboys’ lavish stadium onto the custom-built stage Saturday night in a blue plaid shirt, Wrangler jeans, a silver belt buckle and a black cowboy hat, facing the largest crowd for an indoor concert in North American history.About 105,000 people packed in for the last concert of Strait’s final tour –exceeding the stadium’s official capacity by 5,000– and shattering the previous record set by The Rolling Stones at The Louisiana Superdome in 1981.“I can’t tell you how excited I am to be here tonight. It’s just been on my mind since we started this tour two years ago, and finally it’s here tonight,” Strait said. “We broke a record for the most people, ever. Really? Why wouldn’t we, huh?”Pickup trucks full of tailgaters started to pull into a parking lot across the street from the stadium hours before show time. Fans exchanged stories about seeing the legendary country star over his lengthy career and belted along to hits playing on a car stereo. The show Saturday brings an end to nearly 40 years on the road for Strait, which started in 1975 with the Ace in the Hole Band. And he is doing it in style, having invited several of country’s biggest stars, including Vince Gill, Sheryl Crow, Kenny Chesney and Eric Church.
