You can dance in BOTH circles, one at a time. First be mesameach the chosson, then go dance with them fellow members of your shul. One thing you don’t want – Don’t create any unnecessary controversy and enjoy the simcha with your shul friends. You can also try to pull in the father of the chosson (or kalla) into your shul circle once in a while!
Hatzlochah, and we should only hear of simchas in these hard times.
