And his leadership, direction, and arranging were also integral. He wasn't called the Lone Arranger for nothing, afterall. And I think he was a far better MC and frontman than Don Henley. He had the charisma and personality to speak to the audience and engage them with is funny bits and his introduction of the band and his jokes about the songs and where he was from. He truly kept it light/fun and everyone loved him!
