Oh Happy Day的歌詞如下：
Oh happy day gonna celebrate it up
Yeah, it's that time of the year
Oh happy day gonna celebrate it up
With a brand new celebration
Oh happy day, oh happy day
It's the time of the year when we go out and play
With all the girls and boys and we gonna have a ball
Oh happy day, oh happy day
It's a day for a change
You don't have to be the same
Oh happy day, oh happy day
It's a time for celebration
It's a time for happiness
So come on and let your spirit soar
Oh happy day, oh happy day
Oh happy day gonna celebrate it up
With a brand new celebration
Oh happy day, oh happy day
