Meanwhile has anyone researched and recorded work songs / chants from other sailing communities? On the recent re-airing of Michael Palin's "Around the World in 80 Days" he (and his film crew) catch hitch a lift on a working dhow from Dubai to Bombay
"Michael Palin and his film crew continue their journey in the footsteps of Phileas Fogg. They drive right across Arabia in only 40 hours to make up for lost time. In Dubai they hitch a lift on a very primitive sailing boat [dhow] and come close to danger in the Strait of Hormuz when the engine fails and they drift among the mines sown during the Iran-Iraq war."
The Beeb included much footage of them sailing on the dhow, including shots of the dhow's crew hauling ropes fo song / chants - for real.
