A Hard Day's Night歌词：
It's been a hard day's night
And I've been working like a dog.
It's been a hard day's night,
I should be sleeping like a log.
But when I get home to you,
I find the things that you do
Will make me feel alright.
You know I work all day
To get you money to buy you things.
And it's worth it just to here you say,
You're gonna give me everything.
So why on earth should I moan,
'Cos when I get you alone
You know I feel okay.
When I'm home everything seems to be right.
When I'm home feeling you holding me tight, tight, yeah.
It's been a hard day's night
And I've been working like a dog.
It's been a hard day's night,
I should be sleeping like a log.
But when I get home to you,
I find the things that you do
Will make me feel alright.
So why on earth should I moan,
'Cos when I get you alone
You know I feel okay.
When I'm home everything seems to be right.
When I'm home feeling you holding me tight, tight, yeah.
It's been a hard day's night
And I've been working like a dog.
It's been a hard day's night,
I should be sleeping like a log.
But when I get home to you,
I find the things that you do
Will make me feel alright.
You know I feel alright,
You know I feel alright.
