It’s a 1974 TV commercial for David Live and it’s pretty goofy. It’s but 30 seconds long, so there’s not a lot more to say about it other than it’s pretty goofy.

Here’s a better one from earlier that same year, for Diamond Dogs. The sultry voice-over here is by Cherry Vanilla, Bowie’s then publicist at his MainMan Ltd. management company. She probably produced it, too, as she came from a Mad Men-era Madison Avenue advertising background before Andy Warhol beckoned.
