《12345》的英文歌詞如下：
數數呀 數數呀 One Two Three Four Five
一顆心撲通撲通跳 One Two Three Four Five
真的真的 很快樂 One Two Three Four Five
你的出現 變得好特別 One Two Three Four Five
心情好得 快要炸裂 炸裂
這感覺 無法抵擋 無法抵擋
就讓我 Follow Follow Follow the light
一起飛 Fly Fly Fly higher
跟著我節奏 快點動一動
一起跳 One Two Three Four Five
就讓我 Follow Follow Follow the light
一起飛 Fly Fly Fly higher
一直追追追 追著夢想的尾巴
跟著我節奏 快點動一動
One Two Three Four Five
跟著我節奏 快點動一動
一起跳 One Two Three Four Five
手拉手 一起走 One Two Three Four Five
連呼吸都變得美好 One Two Three Four Five
愛情的美 好需要氧氣 One Two Three Four Five
手牽手一起跳舞吧 One Two Three Four Five
Let it go Let it go
想為你歌唱 一曲送給你 一曲送給你
My love for you will last forever just like the song One Two Three Four Five.
