        Am
        D
        Cadd9 x32030

When I was an astronaut I didn't take my boots, 
When I was a coal miner I didn't know the news, 
When I was a record store I didn't have the blues, 
I travel light and that's the life for me. 

He doesn't care where else he goes, 
He's not gonna take any extra clothes 
or extra shoes to hide his feet 
The ground is dirt, the dirt is sweet 

When I go Londontown I'll stand under a rock, 
Until I know all the time it takes to pack a clock, 
Then I'll flip it over, close the key, and swallow the lock. 
I travel light and that's the life for me. 

He doesn't take his spoon or fork, 
He's seen too many eating in New York, 
He'll use his hands to pick and eat, 
The fruit he finds, he'll find it sweet 

When I was a waitress, I gave away my tips 
When I was a call-girl, I gave away my hips 
When I ran the kissing booth, I gave away my lips, 
I travel light and that's the life for me 

She lives a life like abandoned wind 
Elemental wife, fortune is her friend, 
I smile on a planet and a river made of light, 
she's just a pebble on a waterfall tonight 

When i go to Boston I stand around in jeans 
And save the cash for Levi?s by selling black-market baked beans 
Denim's what I like to wear it has durable seams 
I travel light and that's the life for me 

She just a genius without a thinking cap 
She never pays the rent, she's funny like that 
I don't know what she's on, she's here and gone 
Rides a welcome mat on a jungle cat 

Fur's and silver chairs and shiny things are just a fuss 
We'll eat all peanuts that we steal from the circus 
We'll count the all stars and go to sleep under the bus 
We'll travel light and that's the life for us 

We'll travel light and that's the life for us
We'll travel light and that's the life for us
