Like he did on Monday at the New York Public Library, Pete Townshend broke out his guitar when he did an in-store appearance Tuesday night at Barnes & Noble in the Union Square section of Manhattan in support of this week's publication of his memoir, Who I Am. Whereas Monday it was two lesser known tracks off Quadrophenia -- "I'm One" and "Drowned" -- on Tuesday it was the anthem "Won't Get Fooled Again."
