Bob Marley - Natural Mystic

There's a natural mystic blowing through the air;
If you listen carefully now you will hear.
This could be the first trumpet, might as well be the last:
Many more will have to suffer,
Many more will have to die - don't ask me why.

Things are not the way they used to be,
I won't tell no lie;
One and all have to face reality now.
'Though I've tried to find the answer to all the questions they ask.
'Though I know it's impossible to go livin' through the past -
Don't tell no lie.

There's a natural mystic blowing through the air -
Can't keep them down -
If you listen carefully now you will hear.

There's a natural mystic blowing through the air.

This could be the first trumpet, might as well be the last:
Many more will have to suffer,
Many more will have to die - don't ask me why.

There's a natural mystic blowing through the air -
I won't tell no lie;
If you listen carefully now you will hear:
There's a natural mystic blowing through the air.
Such a natural mystic blowing through the air;
There's a natural mystic blowing through the air;
Such a natural mystic blowing through the air;
Such a natural mystic blowing through the air;
Such a natural mystic blowing through the air.
