I have 3 yeasts saved in the fridge with crown tops on now. I bulk them up in a 1L starter for 2 days before a brew and they come out steaming! I don't expect them to last forever, maybe 6 months, then if I like the yeast I may regenerate again.
The beer is improving nicely. Nearly bright now, a faint aroma (sandalwood shavings?), taste like draught Bass used to taste with a Yorkshire edge to it, pleasant light/smooth mouthfeel and a slight bitter aftertaste.
I had a beer drinking chum round on Sunday... this was his least favorite

, but he loved my porter (based on Batemans Salem Porter) and my session beer (Goldings/styrians) was disappearing fast
