Watching 5 Konkatsu! episodes in a row got me hooked on this song XD Girls, let us hope that we wouldn't have to sing such a song at any wedding LOL

First, you can download the song here, and the whole "Bring it!" album here

Then you can watch some performance:
This is the performance from the show "Bokura no Ongaku", where Tatchan and Nakai came to promote Konkatsu!

Another performance, this one a collaboration with SMAP, very entertaining ROFL:

Here comes the lyrics:

ウエディング・ベル - Wedding Bell　
Track no.: 13
Album: Bring it!

Kanji
ウエディング・ベル　からかわないでよ
ウエディング・ベル　本気だったのよ　
ウエディング・べる　ウエディング・べる

オルガンの音が静かに流れて　「始まる　始まる」
お嫁さんが私の横を過ぎる　「ドレスがきれい」
この人ねあなたの愛した人は　「初めて見たわ」
私の方がちょっときれいみたい　「ずっとずっときれいみたい」

そうよ　あなたと腕を組んで祭壇に
上がる夢を見ていた私を　なぜなの　
教会のいちばん　後ろの席に
ひとりぼっちで座らせておいて　
二人の幸せ見せるなんて
ひと言言ってもいいかな
くたばっちまえ　アーメン

愛の誓いは耳をふさいでるの
指輪の交換は瞳をとじてるの
神父さんのやわらかな通る声が
遠くに聞こえてふらつきそうだわ

そうよ　あなたから指輪を受ける日を
鏡に向い夢見ていたわ
素顔の自分に言ったの　幸せよって
お化粧する娘はきらいだなんて
あの優しい瞳はなんだったの
もいちど言ってもいいかな
くたばっちまえ　アーメン

祝福の拍手の輪につつまれて　「私はしないの」
どんどんあなたが近づいてくるわ　「私はここよ」
お嫁さんの瞳に喜びの涙　「きれいな涙」
悲しい涙にならなきゃいいけど　「そうね　ならなきゃいいけど」

そうよ　もうすぐあなたは私を見つけ
無邪気に微笑んでみせるでしょう
そしたら　こんなふうに言うのよ　お久しぶりね
おめでとう　とても素敵な人ね
どうもありがとう招待状を　
私のお祝いの言葉よ
くたばっちまえ　アーメン

アーメン

English translation
Wedding bell, please don’t make fun of me
Wedding bell, seriously
Wedding bell, wedding bell

The sound of organ quietly flows, “It’s starting, it’s starting”
The bride is passing by my side, “What a beautiful dress”
This is the person you love, “It’s the first time I see her”
It seems I’m a little more pretty, “Much, much more pretty”

Why am I, the one who dreamed of walking arm in arm with you up to the altar,
Made to sit here at the very back seat of the church?
All by myself, watching the happiness of you two
Can I just say one word?
Damn you
Amen

The vow of love blocks my ears
The exchange of rings closes my eyes
The soft voice of the priest floats by, I can hear even from afar
It must have made people feel giddy

I have seen the dream day when I receive your ring
On the other side of the mirror
You said to my plain self: be happy
Because you hated girls who wear make-up
Those eyes were so gentle
Can I say it one more time?
Damn you
Amen

You are surrounded by the ring of blessing applause, “I’m not joining in”
Gradually you’re drawing closer, “I’m right here”
In the bride’s eyes are tears of joy, “Such beautiful tears”
They'd better not change into tears of sadness, “Yeah, they'd better not”

Very soon you will find me
You will show me your innocent smile, right?
And then, just like that, you will say “It’s been a while”
“Congratulations, you are such a wonderful person”
“Thank you for the letter of invitation”
This will be my word of blessing to you
Damn you
Amen

Amen
