What really caught my attention was this little detail:
Her experience recording with him in the studio went very well. She proved to him that she knew was she was doing and he taught her some new helpful techniques on editing which he credited as learning from Don.
Seems to me that, unlike a lot of people in the music business, Glenn is not anxious to get the full credit for everything he does and adoration that comes with it. Even here he says that he actually learned this from Don. I love that about Glenn, although I obviously don't know him. A lot of people (who don't know him any more than I do) say that he has a huge ego, but most of the actual stories I hear about Glenn - or the interviews I read - imply that he doesn't even have an ego.
