I used to love to play and sing this song in the 60s, even though I knew no Hebrew and could only phonetically approximate the non-English portions. Recently I bought the CD with "Aravah, Aravah" and revisited the song in high-quality sound with a good set of studio earphones.

I still don't know what the last verse means, or even if it's any more a legitimate language than the fake Elvish that Enya adds to "May It Be", but as close as my aging ears can come, the end of the song sounds like:

Aravah, Aravah ni
Al yekase tredem
Mechadezch na fa ni
Ef yar ma y'like gedem

Mechadezch na fa ni
Ef yar ma y'like gedem!

Ahhh, ahhh etc

There may be a very soft "r" at the end of the first line ("aravah nir") but there is no "r" at the end of the third line which rhymes with it. "Y'like" may not even be close -- the "y" sound might be something else entirely, maybe even a part of the previous word -- but it's what I used to sing there, and after twenty or thirty passes with my good 'phones, I can't hear anything else.

Am I close enough that someone with linguistic experience can figure out what Lou, Alex, and Glen were really singing?
