Makcklemore, what happened, Caps was broken on your computer or something?
Chassidish is a part of Ashkenaz. Ashkenaz is basically Europe. Chassidim come from Europe. The other part is Litvaks. Sephardim originated from Sfard, which was Spain. For Generations there has been controversy between Ashkenaz and Sephard. Therefore this song was about that they were next door neighbors and they each thought the other one was strange. They each thought this is my minhag and the other has weird minhagim. Then they discovered that they have the same tune for Baruch Kel Elyon on Shabbos and then they realized that they could be friends.
