I've come to realize I'm not much of a fan of cover bands that dress up and mime as the band. It's much more enjoyable for a band of musicians to come together and just put their heart into performing the material. One of the best Def Leppard cover bands I ever saw featured a singer that did not look like Joe, but could scream the shit out of the songs in a way that Joe never could. Most cover bands will have a singer that simply mimics the original singer, which tends to underwhelm me. Own the song and deliver it with conviction.

Definitely do not f**kin do Prayer and shove a mic at the audience. Do what Bon Jovi won't, which is perform that song as if it were brand new and needs to be proved.
