Bowie showing his appreciation for the most compact and tactile camera technology of its day. The camera in question I believe is a Sony Handycam Vision DCR-PC7E (Taken from an excellent interview by Marc Scarpa)
Many people don't know it but david bowie was a big tech nerd. he was always wanting to try all the newest little gadgets. he was the first artist to make their music available online for sale.
David Bowie really is a remarkable extraordinary man Forgetting the Music he's like a futurist He really does embrace the strange ch ch ch changes The way he sees the world is very interesting & mysterious to me sadly
Usually this type of footage is lost or discarded. Very cool you found it or saved it. Bowie was some kind of guy, other than music, actor, he looked so good.
