Are shows performed on board during overnight port stops?

Just thought of this in the context of my upcoming Bermuda cruise – If the ship is staying in a port overnight, are there still shows in the main theater / ice rink / other main venues? With so many presumably staying off-ship for dinner that night and/or roaming around port until late, I'd think the ship would give the entertainment staff a night off, but then again maybe just enough stay on board / come back early on average that they just cover their bases anyway? I'd love some first-hand-experience feedback on this. Partly because it would help me make the judgement call better about buying the drink package. 

How about in the pubs and other smaller public venues? Do those take a night off from live performances, or do they keep those ones going for the people who come back earlier in the evening / never get off the ship? I remember on Freedom that the guy performing in the pub told me he was only there for 7 out of the 8 nights, and got one night off mid-way to get a break. Seems like that overnight in port would be a sensible time to do that if it's standard policy.

I have only been to Bermuda on Grandeur, so I can't speak to ice shows but the main theater shows (meager though they are on Grandeur) still go on and the casino opens up in the evenings while in port.  I can't say for sure that ALL of the bars are open but the ship definitely does NOT "take the night off".  To be honest, Bermuda shuts down like a clam at night so I can't imagine people staying off the ship until late in Bermuda.  I think you will find that it is pretty much "business as usual" on the ship while it's in Bermuda overnight.

I've only done over night ports stops in Europe that included ports in Iceland, Sweden, Russia, and Denmark. In all cases, the entertainment schedule was similar to that as when not in port. The only real difference was that dinners were often open seating like breakfast and lunch.
