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.

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.
