yeah Karen nailed it, that is exactly what i am saying.  why is she trying to sound just like Joan Jett? she doesnt sound like Blondie, Beyonce, Dolly Parton or Janis Joplin on the other tunes, she sounds like Grace.  maybe since the original song is so similar to Grace's sound and JJ's guitar sounds pretty much the same as Potter's in the first place, there isnt much to morph into a "Grace version."  it just sounds like a cover band, it's almost funny.  i mean, they still sound great and all... i think they should soundcheck this one with Cat on vox, Grace on raging back up for the chorus and see how it feels. put that southern twist into this noctcover to make it more their own. i bet it would sound nasty.  Cat's up for belting out a crowd pleaser once a month or so, no?  i think that would be fun as hell
