Oh what the heck, I put his other videos on the Superfreak page, this one is even better.
The blonde in the 1999 video is Jill Jones. Prince had a habit of producing records for his proteges and giving away songs, he was actually very generous that way. Among other things, he wrote the Bangles' Manic Monday. This video has a very 1950s Italian feel.
This one is kind of a joke and an experiment in just how cheap you can build a guitar. The body is dry-erase board over plywood - no finish - with Tolex side binding. Dry-erase board is Masonite covered with Melamine. The neck is 100% Radiata pine, even the fretboard. The "inlays" are glitter and CA glue. The pickguard is the other side of the dry-erase board - 'chalkboard'. The pickup mount is a 57 cent switch plate.
Bending steel is not that difficult. You can make a pretty tight bend up to 90 degrees in up to 1/8″ material simply by clamping it in a vise and hammering it over. To go beyond 90 degrees, say 180 degrees for a truss rod, first bend it to 90 degrees, then heat the elbow and finish the bend. Heat the bend point until it glows orange. For smaller (guitar-sized) materials, a common hand-held propane torch should be adequate. After bending, quench the part quick in water, like a blacksmith in a western movie. You can hold a small part under the faucet. That will restore the strength of the material.
