Sorry about the late reply. Just got back to tribe after a few days.
Best way to check Cheb i Sabbah's schedule is on his website, www.chebisabbah.com. If he is scheduled out of town, then you'll know he won't be there. Usually, either Janaka, DJ Sep or myself will sub for him.
This coming Thursday, since Chebiji is performing out of town with Midival Punditz, Janaka and I will be splitting the night together.
It'll be a great night, come check it.
Chebiji will be back next week though. I'll try to keep posting his schedule here. I just checked his website and it hasn't been updated for September yet, should be soon though.
