There's a midi of the tune in the Digi Trad , along with the lyrics !

(Am) Sand Bags Wind bags (Dm) camels with a (Am) hump

Fat girls thin girls (Dm) some a little (Am) plump

Slave girls sold here (Dm) fifty bob a lump

In the (E) Old Bazaar in (Am) Cairo

Brandy Shandy (Dm) beer without a (Am) froth

Braces laces a (Dm) candle for the (Am) moth

Bet you'd look a smasher in the (Dm) old loin cloth

In the (E) Old Bazaar in (Am) Cairo

(G) You can buy most (Am) any thing

(G) Thin bulls fat cows a (Am) little bit of string

(G) You can purchase (Am) anything you wish

(E) A clock a dish and something for your Aunty Nellie

(Am) Harem scarem (Dm) what d'ya think of (Am) that

Bare knees striptese (Dm) dancing on the (Am) mat

Umpa Umpa (Dm) thats enough of that

In the (E) Old Bazaar in (Am) Cairo

That Chord set seems to work for me , though I am sure it could be improved !
