When I first got inspiration for this song, I sit on the digital piano Casio PX-100 and I was thinking I want to write a song "Kyrie" song for Catholic mass. It took about 30 minutes to finish this song. I wrote this song yesterday (one day before I wrote "Lamb of God") on 13 Oct, 2005. I record this song with Cool Edit Pro software and I decided only using digital piano Casio PX-100 to record this song. When I finish record this song, my wife came in to my 'work' room and I ask her to take her voices also.
Actually this song I wrote in D=do but I forgot when this morning, I record it on C=do

This is all the lyric

C                              F                     C
LORD HAVE MERCY CHRIST HAVE MERCY
C                              F                    G
LORD HAVE MERCY CHRIST HAVE MERCY
F    G         Em  Am  Dm              G    C      
LORD HAVE MERCY CHRIST HAVE MERCY

 (Repeat 2x)

This song I wrote on Oct 14, 2005. This song is called "Lamb of God". I played with Casio PX-100. I played on Am chord. This is all the lyrics

Am              E
Oh Lamb of God
         F        G         C
You take away the sins

           F               G           Am         E
of the world have mercy on us

Am              E
Oh Lamb of God
         F        G         C
You take away the sins

           F               G            Am         E
of the world have mercy on us

Am              E
Oh Lamb of God
         F        G         C
You take away the sins
           F             
of the world
                 G                      Am
grant us peace everlasting peace
               F      G                  A
grant us peace everlasting peace
