Geer became a dedicated activist, touring government work camps of the Civilian Conservation Corps in the 1930s with folk singers such as Burl Ives and Woody Guthrie (whom he introduced to the "People's World" and the "Daily Worker". Guthrie later wrote a column for the latter paper). In 1956, the duo released an album together on Folkways Records, titled "Bound for Glory: Songs and Stories of Woody Guthrie." In his biography, Harry Hay described Geer's activism and their activities while organizing for the strike. Geer is credited with introducing Guthrie to Pete Seeger at the 'Grapes of Wrath' benefit which Geer organized in 1940 for migrant farm workers.
