Just before the record get started theres a small voice recording in Moroccan.
Does anybody know what it says.
If you speak Morrocan or Arabic you may know.

Apparently it doesn't mean anything in particular....

This is from the 4 Way Site:

Q What is Crosby babbling at the beginning of "Marrakesh Express"?
A It sounds like "Whoopa, hey mesa, hooba huffa, hey meshy goosh goosh".
Graham Nash: "It's some Crosby gibberish that we moved from the begining of Guinnevere to the front of Marrakesh Express".
