That old Bilbao moon, I won't forget it soon
That old Bilbao moon, just like a big balloon
That old Bilbao moon would rise above the dune
While Tony's beach saloon rocked with an old-time tune
We'd sing a song the whole night long and I can still 
recall
Those were the greatest (those were the greatest)
Those were the greatest (those were the greatest)
Those were the greatest nights of them all

No paint was on the door (no paint was on the door)
The grass grew through the floor (the grass grew 
through the floor)
Of Tony's two by four (of Tony's two by four)
On the Bilbao shore (on the Bilbao shore)
But there were friends galore (howdy do, howdy do)
And there was beer to pour (chug-a-lug, chug-a-lug)
And moonlight on the shore (and the moon shines above)
That old Bilbao shore (on the shore, not the rug)
We'd sing all night with all our might and I can still 
recall
Those were the greatest (those were the greatest)
Those were the greatest nights of them all

That old Bilbao moon, I won't forget it soon
That old Bilbao moon, just like a big balloon
That old Bilbao moon would rise above the dune
While Tony's beach saloon rocked with an old-time tune
We'd sing all night with all our might and I can still 
recall
Those were the greatest (those were the greatest)
Those were the greatest (those were the greatest)
Those were the greatest nights of them all

(Extra verse not used by Andy Williams)

Those old Bilbao Guys, they loved to harmonise
Who stopped to realise how fast the summer flies
The moon was on the rise, we'd catch the ladies' eyes
And whisper Spanish lies, They never did get wise.

We'd sing the whole night long
And I can still recall
Those were the greatest,
Those were the greatest
Those were the greatest days of them all.
