How would you get from Edmonton to Walthamstow by bus, OF A NIGHT, please, you lot?

I only know how to do it BY DAY, as, when I lived down in Edmonton, (in the twenty-eight years that I lived down there, I NEVER used the night buses, to the best of my knowledge), so frankly, I wouldn't have a bloody clue where to start! I feel ashamed, having to ask this, as an Edmonton boy, born and bred, who lived down there for nigh-on thirty years, man and boy, but like I said before, I never used the night buses, so I wouldn't know how to get back to Walthamstow of a night, once the Tube's shut down. All I do know is that it's the thirty-four opposite Lidl's up The Angel, (but the other side of the road), BY DAY, but that's gonna be no bloody good to me whatsoever BY NIGHT! I'm buggered if I'd know how to do it! Please help, guys. I'd really appreciate your angles on this one, please, guys. Much obliged! Peace and love! Be lucky! :)
