Forgive my ignorance, Reyzl !  I'm eager for knowledge and that's the reason 
why I suscribed to this list and why I ask more questions than I can give 
answers!

"Got un dos kelbl" was only the "subject" of my e-mail!
BTW, I often heard "Dos kelbl" as title for this song...
In any case: thanks for the interesting discussion about "Dona dona".

To this point: another question (and again, please forgive my ignorance!) : 
What is the meaning of the yiddish /hebrew term "Halaka" ? Can it be the 
child's first haircut?
This question is not completely OoT:  I saw the klezmer theme "Bottle Dance" or 
"Folk song" under the title "Halaka". Could this song/dance be used for that 
circumstance?
