"Que Sera, Sera" 是由 Frank Sinatra 演唱的一首歌曲，收錄於1966年的專輯 "In the Wee Small Hours" 中。這首歌的歌詞如下：
Que Sera, Sera,
Whatever happens, happens for a reason.
We may not understand,
But we'll both agree.
When it's over,
If she says I love you,
I'll say, "Que Sera, Sera".
If she says we're through,
I'll smile and say "So long",
And wave my hand,
And I'll be glad I started out on this song.
The sun will shine,
And birds will sing all day,
And I'll whistle through my teeth,
Just like a kestrel on the wing.
And I'll sing, "Que Sera, Sera".
So let's drink a toast to tomorrow,
And all the dreams that we'll remember.
And let's forget about the pain,
For Que Sera, Sera.
So let's say goodbye to today,
And whistle up our wings and take off on a cloudy day.
For Que Sera, Sera.
