... I'm suprised no one has mentioned it....
The link between All The Madmen and the Beatles' Fool On The Hill
1. The title of both deal with mad/foolish people
2.They start with the same three words - Day after day
3. Both deal with someone who prefers to remain mad / foolish than become part of the sane world
and a bit contriived but...
4. The fool is on a hill, the madman is sent to a mansion cold and grey, Bowie's brother was sent to a mansion cold and grey called Cane Hill
I'm invisible and dumb,
no-one will recall me
