Steve learnt it whilst in Egypt with the army. He learnt it whilst playing for belly dancers so it has that Arabic/flamenco beat. (Boom-chacka-chacka-boom chack. Boom chacka-chacka-boom-chack-boom-chack)
Sorry for the nuemonic above. That is the way I hear it. In the second part (after the full stop) the two boom-chack, boom-chack is where the dancer actually moves/steps forward.
Up until Steve's recent tracheotomy he always sang it in Greek as on his album "Journey into the sun."
Keep singing/playing it. It is truely one of my favourite pieces to play!
