I'm worried that the stainless mesh resting on the base of the Gas-fired copper is going to have a damping effect on the rolling action of the boil, it certainly does when tested with boiling water, so this brew is also to see if it kills the roll with wort too.
Seeing as this is a very impromptu brewday I might even throw in 2 packs Safelager W-34/70 and make it a Steam Beer, so instead of being called 'Brown & Sticky' it would be 'Steaming Brown & Sticky'
I quite like the latter naming option 
Its obviously going to be rather a cross-over style American Brown vs Steam Beer.Fermentables:

Its an altered boil alright, it rumbles around to its self and splatters occasionally, seems active enough:

1043/44, Refractometer said I was right on the money at 1045:
Torch held at the back of the trial jar, wort was nice and clear:
Loads of sludge in the copper, the new Mesh Hop-Stopper worked a treat and drained right down:
Maybe not the nicest looking soldering but it blooming well worked:

The Mash was on at 12:25 and I was all cleaned up by about 17:00, it all went rather smoothly
Maybe its time to start using my Plate Chiller as leedsbrew suggested! 2 packs of Saflager W34/70 Yeast pitched at 19-20c I'll leave it on the cold garage floor to cool down overnight and let it go from there.
