The show itself was amazing and it hit me how cool these old guys are. The long beards, the sunglasses, the simple dance moves while playing... they're just legendary. One awesome moment in the show was towards the end when I pulled out a guitar pick I always keep in my wallet and I started signaling Billy Gibbons that I wanted his by pointing at mine and pointing back at his. He threw me his guitar pick and then I threw him mine... he picked it up and then played "La Grange" with it. Billy Gibbons of ZZ Top literally played "La Grange" with my guitar pick, another cool moment for me without a doubt.
