Разобрал ты правильно, насчёт грамматики беспокоиться не стоит сильнее самого Брауни.
Остальное вот, со слуха опять же:
From my childhood - t'were I am now
I ain't no worry, I'll get by somehow
My mama told me, papa told me too -
I was born with the blues
I tell you something, there ain't no joke
I used my <нрзб> my way from home
Mama told me, papa told me too -
I was born with the blues
I used my guitar for my pillow
Hollow log had even been my bed
Blues my only companion
Had the same blues for my meat and bread
I want you to know! Since I began to roam
Pure ole me, I came from a broken home
My mama told me, daddy told me too - I was born…
Don't believe I'm sinking - look what a hole I'm in
Don't believe I love you - look what a fool I've been
But I'm not ashamed 'bout the bad news - I've been living…
Rocks were my mother's father's pillow
Cold groud had even been their bed
Blue skies were their blanckets
And the moonlight was their spread
You think I'm happy, you shure don't know my mind
Smile on my face, heart's bleeding all the time
But I'm not ashamed 'bout the bad news
I was born with the blues
