Proving that you don’t need millions of dollars to make a difference (I’m looking at you, Bono), Bill Popp has been quietly and steadily organizing shows at Kenny’s Castaways to benefit the American Heart Association each year for the past 24 years. That’s as old as the Met’s last World Series trophy. The benefit honors Popp’s father, “Daddy Popp”—his biggest fan and supporter—who died of a heart attack in 1986. Featuring nine acts, the benefit happens on March 11, 6 p.m., 21-plus. billpopp.com.
