Thank you for your help. I was wondering about the flash.

No flash, shoot raw, matrix meter underexpose a bit, don't waste time on shooting jpegs, they will be unrecoverably underexposed. Raw files will have far more headroom for highlights and shadows. You want to record the great colors of the lights - which would be lost if you use flash.
However, if you are including human subjects in the image, a very small amount of fill flash might be in order.
