Aaron Low is a renowned speech pathologist based in Canada, he was recently asked who he'd like to work with
Whose voice box would you most like to get your hands on?
I want to treat Paul McCartney, because I think he's still got it. Singers like McCartney have amazing, genius skills--but they don't exercise their voices. It's not about aging, it's about voice management. My dream is that Paul calls me up and asks if I can make his voice sound youthful, so he can hit the high notes in "Hey Jude" like he used to.

I think it would be worthwhile to start a petition to make this meeting happen . . perhaps there's someone here who can reach someone close to him, either someone at Capitol Records or MPL or maybe his manager Scott Rodger of Quest Management/Maverick
