うわさを信じちゃいけないよ
私の心はうぶなのさ
いつでも楽しい夢を見て
生きているのが好きなのさ

今夜は真赤なバラを抱き
器量のいい子と踊ろうか
それともやさしいあのひとに
熱い心をあげようか

あゝ　蝶になる　あゝ　花になる
恋した夜はあなたしだいなの
あゝ　今夜だけ　あゝ　今夜だけ
もう　どうにも　とまらない

港で誰かに声かけて
広場で誰かと一踊り
木かげで誰かとキスをして
それも今夜はいいじゃない

はじけた花火にあおられて
恋する気分がもえて来る
真夏の一日カーニバル
しゃれて過ごしていいじゃない

あゝ　蝶になる　あゝ　花になる
恋した夜はあなたしだいなの
あゝ　今夜だけ　あゝ　今夜だけ
もう　どうにも　とまらない

Don’t believe those rumours
I’m innocent at heart
I love the life I have
Dreaming nothing but pleasant dreams

Tonight, should I dance with that nice looking guy
Holding the deep red rose?
Or should I give my passionate heart
To that other kind person?

Ah, the night I become a butterfly, ah, the night I become a flower
That night will be up to you, the night that we will love
Ah, just for tonight, ah, just for tonight
I just won’t be able to stop myself

I’ve called out to that someone by the harbour
I’ve had one dance with that someone in the town square
I’ve kissed that someone under the shade of a tree
So then isn’t tonight fine as well?

With the bursting fireworks comes
The agitated, burning need to love
Isn’t it okay if I’ve dressed to impress
For just the one day of the midsummer carnival?

Ah, the night I become a butterfly, ah, the night I become a flower
That night will be up to you, the night that we will love
Ah, just for tonight, ah, just for tonight
I just won’t be able to stop myself
