From the 1979 Cornerstone album, Boat On The River was Styx' biggest European hit. The song features one of the most legendary mandolin solos in rock history, performed by guitarist Tommy Shaw.
In Greek mythology, Styx was a river which formed the bounday between Earth and Underworld.
Take me down to my boat on the river
I need to go down, I need to come down
Take me back to my boat on the river
And I won't cry out any more
