空之境界中黑桐干也在雨中所哼的歌曲是什么?

我也找过 所以我知道
Singing in the rain
是美国电影<<雨中曲>>的主题曲
歌词是I'm singing in the rain
Just singing in the rain
What a glorious feeling
I'm happy again
I'm laughing at clouds
So dark up above
The sun's in my heart
And I'm ready for love
For love
Let the stormy clouds chase
Everyone from the place
Come on with the rain
I've a smile on my face
I'll walk down the lane
With a happy refrain
Singing, singing in the rain
In the rain.
I'M HAPPY AGAIN
I'm Singin' and Dancin' in the Rain
La... 就是吉恩·凯利（Gene Kelly）1952年拍的Singing in the Rain(《雨中曲》)里的歌曲
