Who would Headline A Concert from the following Bands and Why?

As of now, based on concert ticket sales and album sales, the headlining band should be Def Leppard. That is a close call to Motley Crue, so I could see it either way, but I'll stand by Def Leppard. Poison has lately been touring as a second opener (meaning they go on right before the main act, as in this summer with Motley Crue where Crue is headlining). Thin Lizzy has a cult following but could not possibly follow most of these other bands. Whitesnake has a catalog of huge hits but unfortunately David Coverdale may not be able to perform a long enough set to headline these days. I don't even know what to say about Duran Duran. ZZ top would definitely be high on the bill, but again you have to look at recent concert ticket sales numbers.
