有首歌中的歌词是 i love you by the moonlight， 请问这是什么歌啊？

Artist:Nellie McKay
Song:P.S.I Love You
Dear,I thought I'd drop a line.
The weather's cool.The folks are fine.
I'm in bed each night at nine.
P.S.I love you.
Yesterday we had some rain,
but all in all I can't complain.
Was it dusty on the train?
P.S.I love you.
Write to the Browns just as soon as you're able.
They came around to call.
I burned a hole in the dining room table.
And let me see,I guess that's all.
Nothin' else for me to say,
and so I'll close.Oh,by the way,
everybody's thinkin' of you.
P.S.I love you.
I do my best to obey all your wishes.
I put a sign up.Think
now I got to buy us a new set of dishes,
or wash the ones that have piled in the sink.
Nothing else to tell you,dear.
Except,each day feels like a year.
Every night I'm dreamin' of you.
P.S.I love you.
P.S.I love you.
