this song has to be about trucking;
Artist: Otis Redding Lyrics
Song: Sitting on the Dock of the Bay Lyrics
Sitting in the morning sun
I’ll be sitting when the evening comes
Watching the ships roll in (replace ships with trucks)
And I watch 'em roll away again
[Refrain]
Sitting on the dock of the bay (at walmart rdc)
Watching the tide roll away (replace the tide with my life)
I’m just sitting on the dock of the bay
Wasting time (my life)
I left my home in Georgia (dont think he made it in a ten hour drive)
Headed for the 'Frisco bay
'Cause I had nothin to live for
And look like nothing’s gonna come my way (replace with no forkies gonna come my way)
So I’m just…
[Refrain]
Look like nothing’s gonna change
Everything still remains the same
I can’t do what ten people tell me to do (refers to breaking down pallets)
So I guess I’ll remain the same
Sittin here resting my bones
And this loneliness won’t leave me alone
It’s two thousand miles I roamed
Just to make this dock my home
Now, I’m just…
so in my opinion otis was a trucker
