We still have a Sunday night service, actually our pastor did a survey about a year ago on potential format changes, and that was one of the options. The results were about 50/50 but the 50% who weren't necessarily for eliminating it responded with a basic "whatever you feel is best" attitude.
Pastor prayed about it and even though his personal preference was to go to one service, he felt like our Sunday night services were still well enough attended and productive that he couldn't get a release to do away with it.
So, we are holding on to it for now.
Only because I work at the church and I sometimes feel like I never leave here.
