Roll on big mama      Roll on big mama   (Roll on)   I like the way you sing   Roll on big mama   (Roll on)   The night time lets her breathe      Well, the feel of the wheel delivers me   From a life where I don't wanna be   And the diesel smoke with every stroke   Sings a song with a heavy note      And ramblin? is the life I chose   Sittin? here between the doors   And the yellow line a keepin? time   The things that's a runnin? through my mind   Through my mind      Roll on big mama   (Roll on)   I like the way you roll   Roll on big mama   (Roll on)   You are my very soul      On through the snow and the drivin? rain   To the forty-below in Banger Maine   To the hundred-and-ten in the Texas sun   There ain't no road that we ain't run      Up through the Colorado mountain tops   Down to the desert where Reno stops   There ain't no road that we ain't seen   We ain't seen      Roll on big mama   (Roll on)   You're singing out my song   Roll on big mama   (Roll on)   The highway is our home      Roll on big mama   (Roll on)      Hey, anybody got a copy on this silver roadhog?   What's the smokey situation down the way, boys?   My, they're fine, I'm a comin?, I'm a comin?
