I can't think of any oyster songs, but there's always:
Shrimp boats is a-comin',
Their sails are in sight.
Shrimp boats is a-comin',
There's dancin' tonight.
Why don't-cha hurry, hurry, hurry home?
Why don't-cha hurry, hurry, hurry home?
Look here! The shrimp boats is a-comin',
There's dancin' tonight.
