Various International Tournee of Animation programs

OK guys. I'm an animation enthusiast, and I've been trying to c
reconstruct the International Tournee of Animation programs for a while now. However, some of the films shown in these programs are not available online or accessible to me. It would be a great help to find some of these films.

There are a lot of films shown in these programs that have been lost: these are just my priorities.

They are:

Happy Hour
directed by Brett Koth
shown in the First Animation Celebration
Status: no copy found

Instant Sex
directed by Bob Godfrey
shown in the 16th International Tournee of Animation and Outrageous Animation
Status: copy found, but no audio

Alternativa
directed by Roumen Petkov
shown in the 16th International Tournee of Animation
Status: no copy found

The River
directed by Katji Georgi
shown in the 16th International Tournee of Animation
Status: no copy found

The Animated Star-Spangled Banner
directed by Skip Battaglia
shown in the Third Animation Celebration
Status: no copy found

Snowie and the Seven Dorps
directed by Vincent Cafarelli and Candy Kugel
shown in the Third Animation Celebration
Status: copy found, locked behind Vimeo paywall

Bluefields Express
directed by Charlie Fletcher Watson
shown in the British Animation Invasion
Status: no copy found

Fast Food Matador
directed by Vincent Cafarelli and Candy Kugel
shown in the 23rd International Tournee of Animation
Status: copy found, locked behind Vimeo paywall

I Should See
directed by Paul de Nooijer
shown in the 23rd International Tournee of Animation
status: no copy found

Also, the biggest find of all would be uploads of the original VHSs that were released of the International Tournees, Animation Celebrations, and ESPECIALLY the British Animation Invasion.

If any of you can help, I would gladly appreciate it.
