Re-Oxygenate?

I brewed on Monday, but I had old yeast (I found it in my fridge!) that didn't start....so I had to make my way back to the LHBS to get more and make another starter. I aerated the wort, and sealed it in a corny keg where I plan to ferment it.
The question is, should I aerate the wort again before I pitch the propagated yeast? Or (as I assume) the wort is still "aerated" and therefore I should be fine just pitching the yeast and starting fermentation.

I would not aerate again, but I would re-pitch ASAP.
