When Landeck took over chief editorship of the "Making Music Your Own" series from Youngberg and Luening (1970?), a few songs were dropped and others added. Overall, the Landeck editions seem to have a few more songs that the Youngberg editions.

In Book 5, Four were dropped:
Balm in Gilead (spiritual version)
The Captive Princess (Folksong from Chile)
(a very pretty song about a princess, a dragon, and a knight; the dragon frees the princess to the knight because he sang so well)
Handcart Song (Mormon)
Cradle Song (Wiegenlied)
