Gonna Get Back Home Somehow lyrics

(words & music by doc pomus - mort shuman)
Hear that old train whistle
Howling in the night
If that flyers southbound
Everything will be all right

Im leaving now, leaving now, leaving now,
Im gonna get back home somehow

Dont nobody tell me
Babys been untrue
If shes been unfaithful
I dont know what Ill do

Im leaving now, leaving now, leaving now
Im gonna get back home somehow

Never thought that I could miss her so
I never thought I could , now I know

The sound of the old train whistle
Makes me want to cry
Reminds me of that lonely feeling
When I said goodbye

Im leaving now, leaving now, leaving now
Im gonna get back home somehow
