长江七号中 当小主人公和七仔跳舞时 放的那首曲子是什么啊？

是从一首上世纪80年代Bonny M乐队的迪斯科名曲《Sunny》中节选的，而完整的这首歌恰恰也是片尾曲。

顺便给你附下歌词：
歌词是：
sunny
歌手：dusty springfield 专辑：look of love
(bobby hebb)
Sunny, yesterday my life was filled with rain
Sunny, you smiled at me and really eased the pain
Oh, the dark days are done
The bright days are here
My sunny one shines so sincere
Sunny one so true
I love you
Dusty Springfield
Sunny, thank you for that sunshine bouquet
Sunny, thank you for the love you brought my way
You gave to me your all and all
Now i feel ten feet tall
Sunny one so true
I love you
Sunny, thank you for the truth you let me see
Sunny, thank you for the facts from a to z
My life was torn like windblown sand
And then a rock was formed when we held hands
Sunny one so true
I love you
Sunny, thank for that smile upon your face
Sunny, thank you for that gleam that flows with grace
