Pete Seeger appeared at Northrop Auditorium on October 1, 1972.  Here is a touching story from Alan Freed:

During his visit he stayed at a neighbor’s house, a friend of his. Your trusty kid correspondent (me) could not wait to get an interview using his new Sears cassette recorder, an audio device that was yet to be a common item in the households of America.   I recently found what I had thought was the forever lost cassette containing the conversation. He was amazingly patient, especially considering I showed up at the house practically minutes after he had arrived. Following some audio cleanup (the kid had some technical issues during the recording), the 10-minute interview has been uploaded at http://goo.gl/viDHxc

Here is Pete outside the Winters’ home on S. Cedar Lake Road during that visit, and the postcard he sent me a few months following my first celebrity interview.

RIP Pete Seeger.
