The biggest reason I'm pushing for her specifically is that I believe she is the only one out there who can bring back the energy that was present in the No. 4 and Shangri La Dee Da tours. To me personally, as a matter of opinion, I don't care if you are a great singer and can hit all the notes if you don't bring your "A" game stage presence. There is a certain sparkle to STP; yes part of that is certainly sonic, but part of that is the visual aspect of their performance. As I stated before, I've never been a fan of hers, but I can admit she has a great set of pipes, and just as exciting to me is that she certainly wouldn't disappoint in the performance department. Would she sound anything like how we're used to hearing the songs sung? Absolutely not, but that's the beauty of it. She wouldn't be singing Sex Type Thing in that low growl. It would be her own voice and tone. Like someone else said, it wouldn't be like watching someone do live band karaoke so much. Scott Weiland will always be our Bon Scott, but Lady Gaga could very well be our Brian Johnson.
As confident as I am that she is the right person to perform the existing back catalog, I can also say that I have no clue what original material would sound like coming from that group. It's something I can't even imagine really, but I would definitely give it a chance with enthusiasm.
It's just a natural fit if you ask me. I'm sure theres room for one more east coast Italian in this band anyway.
