Recording and production Lyrically, "Mr. Brightside" depicts a true story of Flowers' jealousy and paranoia when he walked into a bar in Las Vegas and found his girlfriend cheating on him. "I was asleep and I knew something was wrong," he said. "I have these instincts. I went to the Crown and Anchor, a bar in Vegas, and my girlfriend was there with another guy." Guitarist Dave Keuning composed the music before meeting Flowers. Flowers then wrote lyrics and composed the chorus after hearing Keuning's ideas. Flowers credits
