I am thinking that he passed an attractive 'White Girl" at "Market and Van Ness" then he gets distracted "Hear the man singing" and she is gone "Look away and she's eastbound, out of sight.".
Then he imagine that she was an alien:
"Dropped here,
By the hand of the Astronaut,
Builder of the pyramids,
The man from outer space.
Innocent farmgirl,
Raised by the aliens,"
