Bart - where are you at?

Sorry ... I've been out trying to make a living, feed my family, you know ... all those unimportant things in life.

I think I may have some materials from Murray Spivak; I dig around and see what I can find.
He is a type of Freddie Gruber in that he had a methodical approach to grip, wrist and arm motion(s). I know he passed away in the early part of the 90's.
Many of you may not know this about Mr. Spivak, but he was a sound designer in Hollywood and worked on countless films such as King Kong, The Sound of Music, West Side Story, My Fair Lady, Spartacus, Tora! Tora! Tora! and Hello Dolly! ... which I believe he got an Academy Award for.
And yes, there is a video out about the guy as a drum instructor. I believe it's self titled ... Murray Spivak ... or something close to that.
Do a little search on Google or something; I'm sure you'll find more out that way.
