I don't think so - based on my video timestamps Woo was played 1hr after Stefan clips - I was there but couldn't say for 100% as someone said they played Woo twice (i don't remember this though happening though honestly). This video has both in near the start and has both near the start as separate clips -

Maybe it was played by another DJ at the same night? Erol Alkan was also performing and he's been known to demo new chems tracks too, he probably played the Woo track at some point in the night
I can't take the hearbreak of you leaving me again
And I'm not the one I was back then, no, no, no, no
One thing I can't take is to sit home all alone
Do what you like, my dear, but I'm not staying home
