What don't you understand? Here are the lyrics, from the DigiTrad:

ME AND BOBBY MCGEE
(Kris Kristofferson)

Busted flat in Baton Rouge, waiting for a train
Feeling near as faded as my jeans
Bobby thumbed a diesel down just before a rain
Rode us all the way to New Orleans
I pulled my harpoon out of my dirty red bandana
I was playing soft while Bobby sang the blues
With the windshield wipers slapping time
And Bobby holdin' hands with mine
We sang up every song that driver knew

Cho: Freedom's just another word for nothing left to lose
Nothing don't mean nothing but it's free
Feeling good was easy, Lord, when Bobby sang the blues
Feeling good was good enough for me
Good enough for me and Bobby McGee

From the coal mines of Kentucky to the California sun
Bobby shared the secrets of my soul
Standing right beside me, Lord, through everything we done
Every night she kept me from the cold
One day near Salinas, Lord, I let her slip away
Lookin' for that home I hope she finds,
I'd trade all my tomorrows for one single yesterday
Holding Bobby's body next to mine

Freedom's just another word for nothing left to lose
Nothing left is what she left for me;
Feeling good was easy, Lord, when Bobby sang the blues
Feeling good was good enough for me
Good enough for me and Bobby McGee

The song is about a man who hitch-hiked around the country with a woman named Bobby McGee. In the first verse, he remembers a time that she got a ride for them, and he played the harmonica while sang for the driver. ( Some people wonder he could have played the harmonica and held hands with her at the same time). In the second verse, he lists many of the places that they traveled and explains that she left him near Salinas,(a town in the agricultural country in California) because she wanted to settle down, and he just kept travelling--In the end, he regrets that he let her go, because being with her and listening to her sing, was the most important thing in her life.

Is that what you wanted to know?
