We had a great time, (and a great turnout) to help celebrate Pete Seeger's 90th Birthday in Ithaca, New York, back on May 3, 2009. You can see photos and a video from the celebration on the webpage that was created for the event: For Pete's Sake, Sing!
For a number of years Jim Harper and Richie Holtz have been co-hosting community sings at the annual Ithaca Festival. Jim created a songbook so everyone can sing and play along. You can download a copy of the Ithaca Festival Songbook here.
