The Rock Island System in 1965.
Cat's in the cupboard and she can't find me
Oh the Rock Island Line is a mighty fine line
Oh the Rock Island Line is the road to ride
If you want to ride, you gotta ride it like you're flyin'
Get your ticket at the station on the Rock Island Line
Maybe I'm right, maybe I'm wrong
Lawd you gonna miss me when I'm gone
Oh the Rock Island Line is a mighty fine line
Oh the Rock Island Line is the road to ride
If you want to ride, you gotta ride it like you're flyin'
Get your ticket at the station on the Rock Island Line
Jesus died to save our sins
Glory to God I'm gonna see Him again
Oh the Rock Island Line is a mighty fine line
Oh the Rock Island Line is the road to ride
If you want to ride, you gotta ride it like you're flyin'
Get your ticket at the station on the Rock Island Line
Moses stood on the Red Sea shore
Smothin' the water with a two-by-four
Oh the Rock Island Line is a mighty fine line
Oh the Rock Island Line is the road to ride
If you want to ride, you gotta ride it like you're flyin'
Get your ticket at the station on the Rock Island Line
