Not supposed to sing the blues

Born in 1963
In the shadow of Kennedy
I'm still a kid when the levee breaks
Man oh man, that's all it takes
And I'm on my way

Boy, you're not supposed to sing the blues
Where you come from
If you walk across those railroad tracks
Son, you're on your own
But all I know is what I feel
And it can't be wrong
Boy, you're not supposed to sing the blues
Where you come from
Where you come from
It's just not done

Back in black and I'm seventeen
I've been told son, let it be
I've got these lines upon my face now
A room at the Heartbreak Hotel, yeah yeah
Oh well, oh well, oh yeah

Boy, you're not supposed to sing the blues
Where you come from
If you walk across those railroad tracks
Son, you're on your own
All I know is what I feel
And it can't be wrong
Boy, you're not supposed to sing the blues
Where you come from
Where you come from
You know it's just not done
