Back in the day, and it is not that far back, in the late 60s. Prince Philip complained long and loud that the royal family could not live on the    mere pittance granted them by Parliament.

Where did the revenues from the Crown Estates go in those days?

Here is all I can remember of a song from that time:---

Sing O Horo, sing O Horee,
The royal family are in penury.

Sing O Horo, sing O Horee,
Wee Anne upon the streets shall be.

The suggestion made was that she would not be spending her time picking up fag ends.
