Sang this at my brother's memorial service:

I feel like missing you today,
Sometimes I just get that way.
Seems like anything I see
Brings back another memory.
I feel like missing you today.
...
I feel like missing you today,
And letting nobody stand in my way.
I'm gonna pull down the shades
And play some old songs.

And the day my Dad was buried:

Nights are long since you went away,
I think of you each hour of the day,
My Buddy, My Buddy,
Your buddy misses you.

Sorry, I forget who wrote this one.
