Roy Clark had a hit with this song.

I've made a small fortune
and you squandered it all
You shamed me till I feel
about one inch tall
But I thought I loved you
and I hoped you would change
So I gritted my teeth
and didn't complain
Now you come to me
with a simple goodbye
You tell me you're leaving
but you won't tell me why
Now we're here at the station
and you're getting on

And all I can think of
is thank God and Greyhound you're gone
Thank God and
Greyhound you're gone
I didn't know how much longer
I could go on
Watching you take the
respect out of me
Watching you make a
total wreck out of me
That big diesel motor
is a-playing my song
Thank God and Greyhound you're gone
Thank God and Greyhound you're gone
That load on my mind
got lighter when you got on
That shiny old bus is
a beautiful sight
With the black smoke a-rolling
up around the taillight
It may sound kind-a cruel
but I've been silent too long
Thank God and
Greyhound you're gone
Thank God and Greyhound
you're gone!
