1st song: Sorry, don’t know!
2nd song:
Do you have a gemara
A Gemara Bava Metzia
My Leibele is starting[?…]
[?…] joy
My gemarakup, my boy!
The song tells the story of a man and his wife who both (independently) use the money they had saved for something significant to them to buy a Gemara for their son who is starting to learn it (resulting in ownership of two Gemaras – one hopes they were returnable). Though this of course bears a resemblance to O. Henry’s “The Gift of the Magi,” if I remember correctly, the incident actually took place. For all that, I don’t know the name of the song or who recorded it. Someone around here should, though.
3rd song:
“Hu Yivarech” – Dov Hoschander
I didn’t know it, but I usually Google the lyric even though you’re not supposed to be able to (because I said so!).
(Perhaps your filter doesn’t allow Google or similar sites?)
By the way, shouldn’t your name be “cozimajew” ?
