Hm. Not many. Let's see: I used to see Keith and Donna Jean Godchaux at my girlfriend's house in their pre-Dead days. Helped Keith move a piano once. Jeannie Bryson (jazz singer and daughter of Dizzie Gilespie and Connie Bryson) used to babysit for my nieces. Sat next to US senator and presidential candidate Paul Simon at a big lunch once. Si Kahn isn't the most famous folksinger in the world, but he has had a few Grammy nominations and whatnot. My wife used to work with him. Likewise, his friend John McKucheon, well known in hammered dulcimer circles, I know via my wife. Got drunk with actor/writer/performance artist Spaulding Gray once. A real character. Met Jimmy Breslin once when I was leafleting outside a New York movie theater. He looked just like Jimmy Breslin. Abbie Hoffman used to hang out at an office where I worked. He liked to say hi to everyone who went in and out. Used to work at a radio station in Noel Paul Stookey's converted chicken barn. Said hi and bye to him once in a while. Met Odetta once when I was volunteering at a show. She asked me to carry her baby. (Her baby was her guitar.) Met Barry "Fish" Melton of Country Joe fame backstage once. He was in a snit. Insulted Ralph Nader over the phone once. Does that count?
