This is all I play for good, its pretty basic but it sounds just awesome!
Just play a G, D, A Minor, and a C throughout the song and it sounds great.
For the bass part just play the same chords.

Intro: G, D, A Minor, C

Lookin' around the house 
Hidden behind the window and the door 
Searchin' for signs of life but there's nobody home 

Well maybe I'm just too sure 
Or maybe I'm just too frightened by the sound of it 
Pieces of note fall down but the letter said (wahow) 

It was good livin' with you (wahow) 
It was good (awwawawa, wahow) 
It was good livin' with you (wahow) 
It was good (awwawawa) 
Good, good, good, good, good, good 

Sittin' around the house 
Watchin' the sun trace shadows on the floor 
Searchin' for signs of life but there's nobody home 
Well, maybe I'll call or I'll write you a letter 
Now maybe we'll see on the fourth of July 
But I'm not too sure, and I'm not too proud 
Well I'm not too sure and I'm not too proud to say (wahow) 

It was good livin' with you (wahow) 
It was good (awwawawa, wahow) 
It was good livin' with you (wahow) 
It was good...awhh, huuuh...so good. 

Awh, wahow 
It was good livin' with you (wahow) 
It was good (awwawawa, wahow) 
It was good livin' with you (wahow) 
It was good (awwawawa, awwawawanh) 

Yeah you were so good 
yeah you were so good 
Yeah....that's right!
