Is there a way to download the book, or does one have to read it on the Scribd website?
If one quasi-pirate site is the same as a confirmed pirate site, then
https://pdfcoffee.com/bill-cosby-accordion-book-pdf-free.html has it too.
It looks like a fellow-musician uploaded Bill C's book to Scribd (which combines legit ebooks with user uploads, so an uncertain mix). No idea where the pirate site got it.
I took a chance and hope I didn't catch anything horrible.
Does anybody know how this document came to be collected? Did Bill Cosby try to have it distributed when he was alive? I don't remember hearing about it. I followed him on earlier

forums, and he had interesting stories. Nice to see them gathered together. Weird there's no copyright page or anything like that.
I quoted Cosby in my own book when Leon Sash told him not to switch to CBA because it "wasn't a musical keyboard."

That quote is included in this download. Looks like it is a compilation of posts from Cosby's website.
His old site is not archived online sadly, but the site menu from 2012 or so can be seen here (the links don't work).

It looks like this document collects that website/blog/comments content. Which is nice. If nobody objects we could probably upload it to the Internet Archive to preserve it and keep it available. Maybe add a few pics and background to make a "cover"?
I'd be curious who put it together and shared it like this though. Not sure who we'd ask for permission.
