I love this song by Ed and it's really quite easy. Same chords as Give Me Love.

Am F C throughout the entire song. No capo, unless you need one to suit your voice :)
[ in_memory ]
Am.                        F
I write this song in memory of
        C
The wayward smile
                                    Am
The boy we wont forget.  
                              F
The soul you took away from us
        C
The river flows
                                     Am
The tears that we wept
            F.     C
Missing you
                                         Am
Is all that needs to be said
                F.     C
More than blue

The words inside my head
Am.            F.              C
And I know that youre gone

The cheeky smile
Of jokes and laughs
The memories of times
We crossed the line
The stepping stones
Across my mind
Washed away
We all now feel so blind

Missing you
Is all that needs to be said
More than blue
The words inside my head

And I know that youre gone

Goodbye
