"Lifeblood" is an Emily Saliers song from the 1986 Indigo Girls EP
I think the last time I heard it performed live was March of 1990
I'm transcribing the lyrics straight off of the lyric sheet from the
EP, not from the song itself
Another night in a successsion
Thinly glued with beer and wine
It's a precarious profession
Every day at work sees your heart on the line
Maybe I should have gone to business school
Or gained myself a respectable trade
Or stayed in childhood where the shade keeps you cool
Making my living selling lemonade
Chorus:

But running through my veins
Are the words and the refrains
As if they were my lifeblood itself
And I can't stay alive on the food of 9 to 5
If my dreams were just old pictures on the shelf

I remember the folks said give it a try
Or you'll never know who you might have been
And just remember, nothing is the end of the world
Until the world comes to an end
Still, there's a point to this philosophy
Of taking a look at who you are
Still sometimes all I have to help me see
Are all the mirrors behind the bar

Chorus
