"We tried to get in touch with these famous men and, not to anyone's
surprise, it was like getting a hold of Elvis Presley. So we will
consider the fact that BOTH of those beautiful videos have been free to
watch on Youtube for a long time and, since we are Not-for-Profit and
educational on a non-commercial website, we hope their forgiveness for
being so bold as to share their creative work, as well as for using the
music as it plays along.

"We will have to lean upon the Copyright Disclaimer Under Section 107 of
the Copyright Act 1976, where allowance is made for 'fair use' for
purposes such as... teaching. Fair use is a use permitted by copyright
statute that might otherwise be infringing. Non-profit, (Not-for-Profit
in our case) educational or personal use tips the balance in favor of
fair use.
