Someone has put a lot of Kingston Trio recordings on YouTube. I never heard Coast Of California before. Here are the lyrics, yeah it's about hidden treasure... but who's "El Diego", what ship was the Clara, was it real?

These 3 guys could make themselves sound like a whole ship's crew singing hearty in harmony, and some of their harmonies were amazing. Nostalgia in spades... I felt it deeply hearing them as a kid back then, and now it's compounded remembering the nostalgia I felt over 70 years ago!

=======================
Coast Of California
Dave Guard / Jane Bowers

There is treasure hidden there on the coast of California
El Diego hid it there when the Clara ran aground
On the coast of California, deep within a cave that's never seen
Treasure, stolen from the Incas, we could capture for the Queen

There's a mountain in the ocean on the coast of California
And deep within its side the tides of night alone reveal
El Diego's hidden cave where we'll plunder the riches of Grenada
While the Spaniard, blind with pleasure, plays ashore in Ensenada

Ah Ah ah ahh
Ah Ah ah ahh

We will sail before the dawn along the coast of California
El Diego is delayed the wine and woman hold their sway
And our map is clearly drawn to the dark and stormy shore
On the coast of California lies a mighty prize of war

Tell not a soul that you have seen me
Breathe not a word of what I say
Tell not a soul that you have seen me
Breathe not a word of what I say...
