Taft's Blues concordance is the source of most lines, yet there are words missing and here and there I'm not sure. Please, help correct and complete this. Thanks. R

Old Rock Island Blues, sung by Lonnie Coleman

I've got the Rock Island blues, waiting for the Rock Island train
I've got the Rock Island blues, waiting for the Rock Island train
I took the Rock Island train and take a Rock Island ride somewhere

I've got a free transportation, looking for the train to ride
I've got a free transportation, looking for the train to ride
I need to ride the Rock Island, just riding to satisfy

If you ever been down, you know just how I feel
Say, If you ever been down, …
If you ever been down, you know just how I feel

I've got the Rock Island blues, waiting for the Rock Island train
I've got the Rock Island blues, waiting for the Rock Island train
I'll take the Rock Island train and take a Rock Island ride somewhere

An' I'm going away, ain't comin' here no mo'
I'm going away, ain't comin' here no mo'
I'm (???) leaving, hang crepe on your door

I've got the rickets and the rackets and my baby's got the Mobile blues
I've got the rickets and the rackets and my baby's got the Mobile blues
I've got the Rock Island blues and I don't know what to do

One thing about these women I cannot understand
One thing about these women I cannot understand
All wear short dresses trying to fool a workingman

I've got the rickets and the rackets and my baby's got the Mobile blues
I've got the rickets and the rackets and my baby's got the Mobile blues
I've got the Rock Island blues and I don't know what to do

Baby if anyone should ask you who composed this song
Baby if anyone should ask you who composed this song
Just tell Lonnie Coleman, done been to your town and gone
