The Broadside Singers was, for practical purposes, Sis Cunningham and whoever was available for the performance or recording. Sis was the publisher of the topical song magazine Broadside. She also wrote the song "How Can We Keep On Moving Unless We Migrate Too?" and many others. Sis sang, played guitar and piano and is playing accordian in the most common photo of the Almanac Singers with Woody Guthrie and Pete Seeger. Bob Dylan was one of the original editors and his "Blowing In The Wind" was the first cover song for the magazine.
