SemiLive: Can't answer how many (if any) in your community would be offended having it held Sunday night, but if there's any question, don't risk it. I assume you want to attract as many in your community to attend, so if you have the option of scheduling it for Monday afternoon (Memorial day), do 'that', and keep everybody happy. The other advantage of holding your show earlier in the day (Monday afternoon), is that older audiences tend to be more attentive then, as following an evening of church sermoning, they may be tired & prefer to just go home. Just my thoughts. Sounds like a fun music presentation that those in your community will enjoy. Would be great if you could post pictures of the event. Good luck. - Scott
