"Go To Sea Once More" has to do with spending one's fishing pay on whores. One verse has the whores laughing at the poor slob who wasted all his money and was forced to ship out again.

"Cathouse Blues" was recorded in 1974 as a demo for the Buckingham Nicks album. Stevie Nicks gave it the old smoky-voiced, Calamity-Jane treatment. Lyrics below:

    Lyrics »

I got the Cathouse Blues...
I wear the highest
of high heel shoes
Whoa, darling, it's hard to be surrounded
Where the women are lazy,
And the men are rude

I got the cat walk, don't talk blues...
I creep on cat's feet,
I don't speak loose
Yourself in velvet,
Forget we ever met...
I got the closed in,
The cathouse blues...

Blue gray eyes that say...
I guess you don't remember
I guess that I was younger
Touche, the cat sleeps alone,
Sleeps only in the sun
But she'll awake at night
And she'll be gone...

Singing the cathouse blues
I need some new red velvet shoes
I'm still a dreamer's fancy...
They say I'm pretty classy...
I'm just a feline silky cat come true...
I'm just a feline silky cat come true...
I'm just a feline silky cat come true
Yeah.
