懷舊的英文歌詞如下：
I'm feeling old
nostalgic
Looking back on the days
when I was young
I miss the carefree
life then
And all the people I knew then
懷舊的心情
如影隨形
回憶往昔
年少輕狂
想念那時無拘無束的生活
和所有熟悉的面孔
英文：Nostalgic mood is like a shadow that follows me everywhere. Looking back on the past, I miss the carefree life then and all the people I knew then.
