Baal Habooze: Oh, you mention Mimkomcha- it reminds me of a funny story last year Sukkos when my whole extended family was at my Sukkah and some one suggested that they sing Mimkomcha- immediately, three different people began three different tunes :).
Whatever zemiros you usually sing will probably work. A bit of alcohol will probably suggest one or two to you 🙂 (I think I’ve been hanging around my cousins too long…).
