"Save your best song/tune 'til last - this is what they'll remember you by"

Actually, showbiz advice is to save your second best till last.

Always start with your best piece; one you're 100% confident with (they need to see you're in control and happy), one that'll surprise and delight (and claim the stage for your set).

You've GOT to hook 'em from the first - or

they may not stay around to hear the last
