Tipping Question

I am so confused as to who to tip. Did anyone tip their band, photo, video at the end of the night? If you are paying for their dinners, so you still have to tip them and if so, what is the amount????
I am sooo up in the air about this still.
TIA!!!

Try a search b/c there are a bunch of threads about tipping and how much different people tipped different vendors. Here are a few:
