Re your comment on EDWARDS, RON "The Big Book of Australian Folk Song" (Rigby, 1976).

Ron also published "Great Australian Folk Songs" through Ure Smith Press in 1991. It is shown in the colophon as "First published by Rigby, 1976."

I think this is the same book. Reference:

Edwards, Ron; "Great Australian Folk Songs;" Ure Smith Press, 1991. Copyright R. G. Edwards 1976. ISBN 0 7254 0861 8; 507 pages, including 92 pages of indices etc; Words, music, collection dates and sources.
