Yes, Hantour is very popular shaabi song in Egypt and even in other Arab countries as well. It, too, is from a Egyptian movie.
Hantour in the name for carriage, the types that horses pull.
The chorus sings tyrgn, tyrgn.. which is the sound for "running horses". The one you teach for kids to do.. In Finnish it's koppoti, koppoti. Do you understand? Like the sound people make with their mouth to sound like the horses hooves.
