Low - death of a salesman

So I took my guitar
And I threw down some chords
And some words I could sing without shame

And I soon had a song
I played it around
For some friends but they all said the same

They said music's for fools
You should go back to school
The future is prisms and math

So I did what they said
Now my children are fed
'Cause they pay me to do what I'm asked

I forgot all my songs
The words now are wrong
And I burned my guitar in a rage

But the fire came to rest
In your white velvet breast
So somehow I just know that it's safe
