... 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
