In fact, Will, I think WKB used BOTH those tunes in their Sand Dance. I have found several versions on Youtube. The Ballet Egyptien tune, IIRC was also used by Horne & Murdoch for their "My aunt's name is Ella Wheeler Waterbottle" series of songs in Much Binding, Round The Horne, &c. It was the feel of Old Bazaar's relationship to that, & to Thornton[attrib] 'Streets Of Cairo' {aka Snake Charmer tune, "In the South of France where they do the hula prance", &c} which makes me think it must be older than Chester et al; but perhaps it's such a good pastiche as to give that impression, at that.
