Okay, i am not a tech whiz like some of the submitters but after watching the video three times it clearly seems to be a guitar problem and not a keyboard problem. Watch how EVH paces around, looks down, turns his back to the audience and tries to re tune mid stream. So while many many groups seems to cheat or at least enhance their live performances i do not think this is a revealing moment a la the pathetic ashley simpson on SNL. that said i agree with the person who said leave me with my memories of these guys from the 80s - DLR jut looks sort of sad. do they really need the money that badly. and for those of you who have the time check on the you tube of gwen stefani falling down in glasgow and watch what happens with her own vocals when she falls down - to my non techie ears the volume goes down but the voice continues - almost as if she was using a backing tape of herself in conjuction with her own voice during the concert - of course it is easy to criticize and i would love to have five percent of the talent of all of the performers mentioned above (except ashley simpson)
