以下是"Chipmunks Happy Birthday Song"的歌詞：
Happy birthday to you
Happy birthday to you
Everybody sing with me
Happy birthday to you
We'll have fun today
And make a day extra special for you
With presents and balloons
And a cake with candles too
Happy birthday, dear [name],
Happy birthday to you
Make a wish and blow out the candles
Happy birthday to you
We'll sing this song for you
And then we'll all dance and have fun
And then we'll all sing again
Happy birthday to you
