Uniondale 1973, Super 8 Footage

[BloxyTiger]

In 1973 Elvis performed 4 shows at the Nassau Coliseum in Uniondale, New York
These are some of what I consider to be Elvis' best shows of 1973

During those 4 shows, atleast 2 fans attended all shows and filmed all four shows, all their films are public

But, also these two Super 8 films from June 22 and June 23 ES exist, of which exist no public transfers

Does anyone know anything about these films?
The information I have is:
- Footage is Super 8
- The footage is owned by private collector Ernst Jorgensen
- The filmer filmed at least 2 shows

Any help / new information would be really useful, thanks for reading!
