SHA LA LA　いつかきっと　僕は手にするんだ
はかなき　胸に　そっと　ひかり　燃えていけ

逢いたくなるの「衝動」哭きたくなるの「純情」
夏の火に飛び込んだ　ホタルはかえらない

あなたは何も言わず接吻(くちづけ)を残して
火傷(きず)つくまま　うなづいたね
哀しいほど命　揺らめいていた

SHA LA LA　いつかきっと　僕は手にするんだ
はかなき　胸に　そっと　ひかり　燃えていけ
SHA LA LA　愛しきひと　あなたもみえているの
まばゆい　月が　そっと　明日を照らして
強く　強く　輝いて

風に吹かれるほど　烈しくなる心に
はぐれそうな想い出が　また優しく灯る

夢中で駆けだしたら　触れられる気がした
意志(おもむ)くまま　手を伸ばすよ
切ないほど命　揺らめいていく

SHA LA LA　僕はずっと　唄いつづけていくよ
ふるえる　胸に　そっと　ひかり　燃えていけ
SHA LA LA　愛しきひと　あなたに届くように
はてない　空に　そっと　想い　つのらせて
強く　強く　響かせて

SHA LA LA　いつかきっと　ホタルは燃え尽き散って
きえゆく　胸に　そっと　夢よ　輝いて
SHA LA LA　愛しきひと　あなたも忘れないで
きらめく　夏に　そっと　願いを重ねて

SHA LA LA　いつかきっと　僕は手にするんだ
はかなき　胸に　そっと　ひかり　燃えていけ
SHA LA LA　愛しきひと　あなたもみえているの
まばゆい　月が　そっと　明日を照らして
強く　強く　輝いて

Sha la la I know that someday
I will find what I'm chasing after
I pray that light will shine into your heart
and set your empty soul ablaze

My desire to see you just once more
Is so strong I cry till my heart's torn
Fireflies have flown into summer
And they will never come back again

You left me with a kiss on my lips
And told me that you had to go
And although I was sad
I just nodded my head
And then you walked away and left me
I trembled and cried with grief

Sha la la I know that someday
I will find what I'm chasing after
I pray that light will shine into your heart
and set your empty soul ablaze

Sha la la my dear beloved
I can still see your precious smile
the dazzling light shining from the moon
Illuminates tomorrow's way

Let it shine, let it shine, to brighten your way

Memories of my past have faded
As I let my heart grow cold and bitter
But the thoughts of time I spent with you
Gently bring back those memories

Sometimes I wish if I held out my arms
That I could hold you close once again
But when my mind returns from that fantasy
My heart is filled with pain and I feal
As though I cannot go on

Sha la la I will forever
Sing the songs of love within my heart
And now within my shaking heart beat
The light is shining once again

Sha la la my dear beloved
Don't you see that I'm reaching for you?
The song of love that I'm singing to you
Resounds throughout the endless sky

Let it sound, let it sound, and guide you on your way

Sha la la I know that someday
The Fireflies will no longer shine
And though my heart is quietly fading
A light still shines within my soul

Sha la la my dear beloved
Promise me you'll always remember
The love we shared on that shining summer
No matter how far off you go

Sha la la I know that someday
I will find what I'm chasing after
I pray that light will shine into your heart
and set your empty soul ablaze

Sha la la my dear beloved
I can still see your precious smile
the dazzling light shining from the moon
Illuminates tomorrow's way

Let it shine, let it shine, to brighten your way
