I can't transcribe the song right now because I'll disturb my student. I'll get to it later. Here are the lyrics from zemerl.com:

Shir HaBokrim
(M. Nozyk and Y. Orland)


Arava arava ein ketz
Ein habokrim tara
Lo arar lo dardar lo ets
ruach ba hamidbara

Lo arar lo dardar lo ets
ruach ba hamidbara

Zemer habokrim yaale v'yivka
al merchavim avudim ad en gemer
v'tizrach hachama v'tishka
umosif v'koleach hazemer

Arava, arava ein ketz
Shnot alafim kamu
Haboker al gav sus kadmon
Badrachim shenashamu

(translation - Literal, not poetic)
Desert, desert without end
The cowboys' eyes survey it
No juniper, no thistle, no tree
Wind coming from the wilderness

The cowboys' song rises and falls
Over an empty, endless expanse
The sun rises and sets
And the song continues to flow

Desert, desert without end
Arisen over thousands of years
The cowboy astride his Arabian [aboriginal horse]
Over roads that breathe
