What I've called Em7/G is similar to the open G shape, the notes being G, (A muted), E, G, D, E. 
What I've done below is the best I can for a song that was designed for piano and not guitar.
Verse 1:
	
	Em7/G           Dm7/C  
	Where  did your long hair go
	Em7/G                Dm7/C  
	Where  is the girl I used to know
	Em7/G           Gm7       Gm7/C FM7/C
	How   could you lose that happy glow
	             FM7
	Oh Caroline, No
Verse 2:
	
	Who took that look away
	I remember how you used to say
	You'd never change, but that's not true

	Oh Caroline, you
Bridge:
	
	        Dm7  G9   CM7
	Break my heart, I want to and cry
	       E7sus4b9   E7      Am7
	It's so sad to watch a sweet thing die
	             Fm6
	Oh Caroline, why
Verse 3:
	
	Could I ever find in you again
	Things that made me love you so much then
	Could we ever bring them back once they had gone
	Oh Caroline, no
