Chassidic dance sets?

[MaxwellSt <MaxwellSt...>]

Dear fellow klezmer jobbers,

Here comes another chassidic gig, and a list of requests that I have never 
heard of: Ani Ma'amin, Samachnu Mi Elokeynu, Nigun Va'itin, L'Binyamin, Hazak
,,,,The client is dumbfounded that we don't know these smash hits.  Where 
does a poor motley klezmer band with an aging book of "best Chassidic hits" 
and a fake chart of Modim and Moshiach go to find these musical wonders?  Any 
clues?
