Translation of the song 初演 [Opening] artist The Nightmare Before Christmas (OST)

昔々　かなり大昔のことを

Once upon a time, a long time ago

君たちが夢で見たような場所だ

There was a place you might have seen in a dream

今からお話するこの出来事は　ホリデーワールドで起こったこと

From now on, I will tell you of an event that happened in the world of holidays

ホリデーがどこから来たのか　知ってるかな

Have you wondered where holidays come from?

知らない

You don't know?

でわ今からその答えを説き明かそう

Now you'll learn the answer
