Kammen tunes

[Linda Littleton <lrl...>]

My band is planning to record three tunes from Kammen book 1, and I'm
wondering if anyone out there can help out by providing any info on
them.  The three tunes are:

Num 1  - Frailach (Jewish Dance)
Num 13 - Rumanian (Jewish Horra)
Num 20 - Kolomeika (Ukranian)

None of these list authors, so can I assume they are traditional?  On
the first tune, there's a 1951 copyright listed by J & J Kammen.  Would
that have expired by now or do they hold copyright to this tune and
perhaps the others as well?

Anyone know of names to these tunes?  The first tune I think I've heard
of as "Mazel Tov," but am not sure.  What does "Kolomeika" mean?  Is that
the name of the tune, or is it a dance form, or something else?  Not
really sure what else to ask, but if you can answer any of my unformed
questions, that would be great]
