Yacht Club Bar Song, ChorusI love to sit around the yacht club bar
and talk about the things we’re going to do.
I love to sit around the yacht club bar
because it doesn’t move.
The swells are big and the winds are high
but that don’t bother me.
Cause I never get lost and my tummy doesn’t toss
It’s a wonderful life on the sea.

Yacht Club Bar Song, Verse 3
My head it was a reeling, my feet got tangled up.
Those damn old sheets were everywhere, just trying to trip me up.
The halyard broke, the boom fell down, the main took off like a bird.
Mayday was my final cry as I dived beneath my berth.
