"You're the stretch of the beach the tide doesn't reach" is fascinating to me. It makes me think Kick the Bride is about The False Bride. Everyone knows the sun is the man and the moon is the woman. The moon controls the tide. So if the bride in the song is the stretch of beach the tide doesn't reach, she's not truly "lunar," she's like a zombie bride which might explain the kicking.
Googling false bride looking for another article, I found this interesting link to a song published in 1959 called "The False Bride" published in a Penguin Book Of English Songs which is sort of like Kick the Bride AND Oboe Concerto in summation.

I once loved a lass, and I loved her sae weel
I hated all others that spoke of her ill;
But noo she's rewarded me weel for my love,
For she's gaun to be wed till anither.
When I saw my love to the church go,
Wi' bride and bride-maidens, they made a fine show;
An' l followed them on wi' a heart fu' o' woe,
For she's gaun to be wed till anither.
When I saw my love sit down to dine,
I sat down beside her and poured out the wine,
An' I drank to the lass that should ha'e been mine,
An' now she is wed till anither.
The men o' yon forest they askit o' me,
Hou many strawberries grew in the saut sea?
But I askit them back wi' a tear in my ee',
How many ships sail in the forest?
O dig me a grave and dig it sae deep,
An' cover it over with flow'rets säe sweet,
An' I'll turn in for to tak' a lang sleep,
An' may be in time I'll forget her.
They dug him a grave an' they dug it sae deep,
An' covered it over with flow'rets säe sweet,
An' he's turned in for to tak' a lang sleep,
An' maybe by this time he's forgot her.
I'll try to find that other article on False Brides. Sometimes it seems like he's singing from the perspective of empathizing with her and then hating her. It's a challenging song. I have some other ideas.
