4 am Saturday Morning (good time to play?)

I generally go out and play live on Friday nights between about 7pm and 2 am. However, I am not able to get out of the house until after 2 am tonight. If my tiredness is not a factor, are the table still full of fish at 4 am Saturday morning? and if so, what time does it become a rock garden? I have played on Saturday afternoons and have been met by the geriatric tighties.
