He is a liberal labor activist and singer-songwriter.
I noted that the concert was sponsored by Duncan Earle, then a young faculty member, known for his liberalism. I recently connected with him, Earle, by email.
Today I got news, meanwhile — because I reached out — that Si Kahn won a Joe Hill Labor Award. They circulated a photo of him next to a Mother Jones memorial in Southern Illinois (I’ve visited, and shot).
The mention of Joe Hill reminds me that I mean to present the Wayne Horvitz oratorio on Joe Hill that includes Wallace Stegner, Paul Magid, Bill Frisell, Robyn Holcombe, Danny Barnes and Rinde Eckert.
If Si Kahn is in the area, I might persuade him to busk at Lytton Plaza.
