A Mighty Day (Chad Mitchell Trio)
I remember down in Galveston, When storm winds swept the town, The high tides from the ocean, Lord, Put water all around.
[Chorus:] Wasn't that a mighty day, (a mighty day) a mighty day (a mighty day) a mighty day, great God that morning When the storm winds swept the town
The winds began to blowin'. The rains began to fall. The lightning shafts were cracklin', Lord, And the thunder started to roll
[Chorus:] Wasn't that a mighty day, (a mighty day) a mighty day (a mighty day) a mighty day, great God that morning When the storm winds swept the town
The trumpets warned the people, "You'd better leave this place". But they never meant to leave their homes Till death was in their face.
The seas began to rollin'. The ships they could not land, I heard a captain crying, "God, Please save this drowin' man!"
Chorus:] Wasn't that a mighty day, (a mighty day) a mighty day (a mighty day) a mighty day, great God that morning When the storm winds swept the town
The trains they all were loaded With people leavin' town, The tracks gave way to the ocean, Lord, And the trains they went on down.
The waters like some river They went a-rushin' to and fro I saw my father drownin', Lord, And I watched my mother go
Chorus:] Wasn't that a mighty day, (a mighty day) a mighty day (a mighty day) a mighty day, great God that morning When the storm winds swept the town
Now death your hands are icy. You've got them on my knee. You took away my mother now. You're comin' after me.
[Chorus:] Wasn't that a mighty day, (a mighty day) a mighty day (a mighty day) a mighty day, great God that morning When the storm winds swept the town
[Chorus:] Wasn't that a mighty day, (a mighty day) a mighty day (a mighty day) a mighty day, great God that morning When the storm winds swept the town
