Ladysmith Black Mambazo

I just heard Ladysmith Black Mambazo's manager, Mitch Goldstein, say on the radio that he was the one who suggested that the South African a cappella group sing "Old MacDonald Had a Farm" on their new album, Songs from a Zulu Farm.  I wonder whether that might, perhaps, be considered a little bit patronizing and infantilizing?  Would the conductor Valery Gergiev's manager suggest that he record "Three Blind Mice"?  Would Radiohead's manager suggest that the band cover "Itsy Bitsy Spider"?
