"Yes, you want her,
Look at her, you know you do,
Possible she wants you too,
There is one way to ask her,
It don't take a word, not a single word,
Go on and kiss the girl, kiss the girl, girl-"
"Sha-la-la-la-la, my oh my!
Look, that boy's too shy,
Ain't gonna kiss the girl,"
"Sha-la-la-la-la, ain't that sad?
It is too bad,
You're gonna miss the girl,
You're gonna miss the girl,"
"Now your moment,
Floating in the blue lagoon,
Boy, you better do it soon,
No time will be better,
She don't say a word, no, she don't say a word until you kiss the girl,"
"Sha-la-la-la-la, don't be scared,
You got the mood prepared,
Go on and kiss the girl,
Sha-la-la-la-la, don't stop now,
Don't try to hide it how you wanna kiss the girl,
Sha-la-la-la-la, float along,
And listen to the song, the song says "kiss the girl,"
Sha-la-la-la-la, let the music play,
What that music say? you gotta kiss the girl, kiss the girl,"
