This is the song I actually wanted for the interclass karaoke.
Its not difficult except for the 合声 part,
but otherwise it's fine and can make the atmosphere high also.
Its a quite old song alr, but anyway we can modify to make it suit our style.

Presenting... Please Mr. Postman!!!



( Stop )
Oh yes, wait a minute
Mister Postman
( Wait )
Wait Mister Postman

(*)
Please Mister Postman look and see
( Oh yeah )
If there's a letter in your bag for me
( Please, Please, Mister Postman )
Why's it takin' such a long time
( Oh yeah )
For me to hear from that boy of mine

There must be
Some word today
From my boyfriend
So far away
Please Mister Postman
Look and see
If there's a letter
A letter for me

I've been standin' here
Waitin' Mister Postman
So patiently
For just a card
Or just a letter
Sayin' he's returning'
Home to me

Repeat (*)

So many days
You passed me by
See the tears
Standin' in my eyes
You didn't stop
To make me feel better
By leavin' me
A card or a letter

Repeat (*)

( Why don't you check it and see one more time for me you gotta )
Wait a minute, wait a minute...
( Mister Postman )
Mister Postman look and see

( C'mon deliver the letter, the sooner, the better )
Mister Postman

It's a really nice song, rite? ;-)
