Once in a Lifetime的歌詞如下：
Once in a lifetime
Once in a lifetime
Once in a lifetime
You've got to know
Once in a lifetime
Once in a lifetime
Once in a lifetime
You've got to go
And I've been waiting for you
I've been waiting for you all my life
You're the only one for me
I've been waiting for you to say it
I've been waiting for you to show it
You're the only one for me
It's been a long time coming
But I know that I will see you again
But till then I'll believe it
I've been waiting for you to say it
You're my destiny, my guiding light
I'll follow you till the end of time
I've been waiting for you to show it
You're the only one for me (and) you and me forever now baby, that's how it has to be, oh no no oh, gotta keep the faith (no doubt) yeah yeah oh oh yeah, 'cause you know we both belong, you and me forever now, that's where we belong.
Oh no no oh, gotta keep the faith (no doubt) yeah yeah oh oh yeah, cause once in a lifetime, once in a lifetime, once in a lifetime, you've got to know. Once in a lifetime, once in a lifetime.
