Two series of songbooks not yet listed are:

"The American Singer," Books 1-6, 1946, John W. Beattie, Josephine Wolverton, Grace V. Wilson and Howard Hinga, American Book Company.

This series was also printed and bound in Canada as "The Canadian Singer," Books 1-6. 1947, W. J. Gage & Co., Ltd., Toronto, without change in content.

"The New Highroad of Song," Books 1-6, and also 1-2-3 in one volume, no date but 1950s, G. Roy Fenwick, Hollis Dann and Robert Foresman, printed in Canada by W. J. Gage and Company Limited, Toronto, Canada.
Only one Canadian folksong and "God Save the Queen," otherwise similar to American school songbooks and perhaps a Canadian printing of an American Series with only the title changed.
