Hi, Rusty!
"Kaiser Bill", I think?
But as you say, probably we shall never know the origin of the phrase!
I didn't know the meaning of "yonks" either...I seem to remember your explaining it to me!
I have been up and down the ladder all afternoon , trying to clear out and reorganise a top cupboard over my wardrobe.
There were two suitcases up there full of "goodies" ....bags, scarves , gloves , belts ....
Items that hadn't seen the light of day for years!
There is a lot of stuff to take to the charity shop!
Now I have to decide what to put up there this time.....!
Strange...my daughter hasn't phoned me , and it's gone past four o'clock...
Usually she rings every day on her way home.
I shall text her to check all is okay.
