Regarding the history of Oak Publications I'm having difficulty sorting out the relationships of a company called People's Artists Inc. which published The People's Song Book, Lift Every Voice (The Second People's Song Book) and the Songs of Joe Hill probably others) in the 1950's and to Sing Out! and to Folkways Records. The earliest Oak publication I have found is about 1961. Some names appear on the editorial staff of all of these - Moses Asch, Irwin Silber, Jerry Silverman, Pete Seeger. Does anyone know the history ? of these.
