A-yup to all that KC and Tek.  And if you're a show dork like me, you always arrive early enough to catch the openers. You arrive so early you get a position right at the front of the stage. If it's an all-ages show, your old ass will ultimately be pushed out of the prime position by annoying, young, hipsters, wearing sweaters with kittens on them, and jeans that are too tight for my 5 y.o. nephew, and they'll have incredibly sharp elbows jutting from their bodies and into the soft, fleshy tissue of your breasts, until your retreat to the safe recesses where those with some experience, courtesy, manners and self awareness reside.  BUT.  I digress.  The up-side of this situation, is that you are often pleasantly entertained by a band you've never seen before or maybe you've never heard of.  And then you start following them, and then, and then. 

The End.  

P.S. Check out Benyaro (Folk) saw them as first of two openers for Steve Taylor at Indy in SF.  Theory proven.  Yer welcome.
