THAT SONG!! HELP??!!

It's sung before and after Dylan goes up the roof and have a chat with Patrick
It says:

Dear Mother, it's been so long
Since I had to say goodbye
They say time flies but I must say
Sometimes it just crawled by
I still think about you every day
I hope that comes as no surprise
How I would love to see you now
What I wouldn't give
But life did not bend to my wishes
And so I had to learn to live...
Dear Mother, I know I'm not the only one
Who had someone taken away too young
Still, that doesn't make it feel alright
To not have had you then and still not have you now
I still think about you every day
I hope that comes as no surprise...

I tried searching A LOT for this!!
