Cleve Pettersen, a Minneapolis man, made a reel-to-reel tape of Bob Dylan singing traditional folk songs in 1960–a full two years before Dylan made any formal recordings. Pettersen has recently donated the tape to the Minnesota Historical Society, where fans can listen to CD and cassette copies of it. Fans are not permitted, however, to make or purchase copies of their own.http://story.news.yahoo.com/news?tmpl=story&cid=495&ncid=495&e=12&u=/ap/20050114/ap_en_mu/people_bob_dylan
