Given that the books have melodies for every song, the value of the books in regard to non-French songs should not be discounted. The lyrics in the original language--or translated into singable English, however fancifully--can probably be found from other (online) sources, but finding the tunes elsewhere may be more problematic. Indices like this also furnish a good starting place for people wanting to add more foreign-language songs to their store. Ainsi, merci beaucoups à Monique et Q!
