Lyric discussion by midnightcarousel 

I'm a bit surprised by how many people think the "wedding" might/does refer to an actual wedding.

The wedding here is not between the narrator and somebody else, it's between the night and the day:

But my laughter turned round, eyes blazing and said "My friend we're a-holding a wedding" I buried my face but it spoke once again "The night to the day we're a-binding" Now the dark air's like fire on my skin And even the moonlight is blinding

His "laughter" is essentially punishing him for being so irresponsible with his lifestyle, and he is no longer able to seek refuge in the night like he once was.
