memo to Zita:
re: "or were they in the bathroom or something when the brains were distributed? It certainly would be most informative to have both discussions side by side and compare notes as to where Mssrs. Nyman and Mazzone agreed and where they disagreed or came to different conclusions. If I wanted to hear stories..."
-------So, you're an outstanding musician, right Zita? Do you normally allow your stage performances to be videotaped for distribution without your permission? (Hint: Whether you personally care or not, the promoters and/or venues you play for most likely do have policies forbidding unauthorized recordings of your performances. Most reputable programs for expert speakers would routinely forbid people from doing this as well....especially for any kind of distribution beyond personal use.
So, practically speaking, unless someone is really motivated to team up with others, make illegal videotapes, and share them...your no-brainer idea is not very practical.
All of that aside, anyone with reasonable fore-knowledge of Mazzone and Nyman could readily decide which seminar they would rather attend...their style and content are as different as baroque and ska.
