Say, you'd better apologise to my mule

This is Alby during a trek along the side of the Andes (Peru) in search of a village from which he and his cameraman could catch a train to Lima, in the latter stages of WSII. He reports that by this time he was thoroughly sick of donkeys, but there's few beasts of the world that Alby doesn't look right at home with. He's a natural.
