By and large, many agree that the Queen's Death is referred to by the higher ups as the "London Bridge" event.
The "My fair lady" bit is the connection why.
But look at the other lyrics...
There's more than meets the eye.
London Bridge is falling down
Falling down, falling down
London Bridge is falling down
My fair lady
Build it up with iron bars
Iron bars, iron bars
Build it up with iron bars
My fair lady
Iron bars will bend and break
Bend and break, bend and break
Iron bars will bend and break
My fair lady
Build it up with gold and silver
Gold and silver, gold and silver
Build it up with gold and silver
My fair lady
Gold and silver we've not got
We've not got, we've not got
Gold and silver we've not got
My fair lady
London Bridge is falling down
Falling down, falling down
London Bridge is falling down
My fair lady
London Bridge is falling down
Falling down, falling down
London Bridge is falling down
My fair lady
What holds up a bridge?
A Truss.
So when Truss visits the Queen then departs... ruh roh.
Just a guess.
Interesting!
Nice catch!
