Stay (Maurice Williams & Zodiacs)
在明宇和童珍约会后在雨中玩水的时候出现还有一起打算开车~不走公路,只走土路~的旅行时也出现
另外最近在杨千桦和eason陈的广告里也用了这首曲子

歌词:
A-a-a-a-ah, just a little bit longer
(Please)
Please, please, please, please
Tell me you\'re going to
Now, how your daddy don\'t mind
And your mommy don\'t mind
If we have another dance
Yeah, just one more
One more time
Oh, won\'t you stay
Just a little bit longer
Please let me hear
You say that you will
Say you will
Won\'t you press your sweet lips
To mine
Won\'t you say you love me
All of the time
(Stay) <
