The Beatles - Now and Then

I know it's true
It's all because of you
And if I make it through
It's all because of you
And now and then (Ah-ah)
If we must start again (Ah-ah)
Well, we will know for sure
That I love you
I don't wanna lose you, oh no, no
Abuse you or confuse you
Oh no, no, sweet darlin'
But if you have to go (Go), away (Ah-ah-ah)
If you have to go, well you the reason [?]
Now (Now) and then (And then)
I miss you (I miss you)
Oh, now (Now) and then (And then)
I want you to return to me
'Til you return to me
