Fixing the Moto Guzzi V85TT rear shock squeak issue

Squeak, piggy, squeak. After only around 3000 miles, my bike developed "the squeak". A not uncommon problem on the V85TT sadly. Luckily it's an easy fix if you've got a few simple tools and half an hour to spare.
Although it's a simple process, I thought some people might find it useful to see how I fixed it on my bike.
Disclaimer: I am not a mechanic, this is just how I did it!
As there's not much room in the Fat Cave (tm) I had to clear a space in the Shed of Dreams (tm) in order to be able to film and spanner at the same time.
