Luke Bryan's summer tour is having a rough week. Following Sunday's show at New York's Jones Beach Theater, Bryan apologized for struggling on stage with his voice. He tweeted, "Gave you all I could. What's crazy is my allergies. I focus all day to sing good. And some days the kitchen sink won't work. Then you just drink tequila. Ha." Bryan's tour took another hit yesterday morning when one of his equipment trucks crashed into a New York overpass. Thankfully, no one was injured in the accident.
