These lyrics can be found in many traditional songs. They may be from an old English ballad. The tune suggests West Indian origin. In any case it’s a woman who has lost her loved one to the sea and hopes he will return.
Lyrics:
[G] Deep [C] Blue [G] Sea, Baby, [C] Deep Blue [G] Sea
[G] Deep [C] Blue [G] Sea, Baby, [Am] Deep Blue [D] Sea
[G] Deep [C] Blue [G] Sea, Baby, [C] Deep Blue [G] Sea
It was [Em] Willy [G] what got [Em] drowned in the [G] Deep [D] Blue [G] Sea
Dig his grave with a silver spade (3x)
It was Willy what got drowned in the Deep Blue Sea
Lower him down with a golden chain (3x)
It was Willy what got drowned in the Deep Blue Sea
Wrap him up with a silken shroud (3x)
It was Willy what got drowned in the Deep Blue Sea
Deep Blue Sea, Baby, Deep Blue Sea (3x)
It was Willy what got drowned in the Deep Blue Sea
