Did you know Joan and Mimi could sing cuecas, and that they sang this Bolivian anthem at the 1972 concert with B. B. King at Sing Sing? I discovered it while looking for Peruvian cuecas. Here is some commentary on the song by Rockoblogia:
De la canción escrita por Apolinar Camacho: El boliviano tocó las puertas para nacer en Uyuni, el 5 de enero de 1917, intentó ser músico profesional pero el dinero solo le alcanzó para tocar un año en el conservatorio. Sabía poco, muy poco de música, lo único que quizás le daba sentido a sus canciones era Dios, como él decía “Mis composiciones provienen de lo alto (de Dios) y gracias a que pienso en cada detalle de mi patria: un río, una india, una chola”.
Su piano, una noche solitaria, su Dios y su patria confabularon para que escribiera las melodías más perfectas para la tierra que lo viera nacer. La cueca nacida en 1939 acompañó a los bolivianos en los momentos más dolorosos y los más alegres, con un letra simple y los acordes de cueca sencillos ¡Viva mi patria Bolivia! se hizo el segundo himno boliviano.
Look at the audience in the video – I think there is at least one Bolivian. I have to go to Angola twice this month, and looking at this prison concert is a good way to get ready. If you follow the link, you can hear the Angola Gospel Superiors sing.
Axé.

beautiful.
I’m so sorry to see the video is no longer available!
Here is another of the same song – less ethereal but authentic in another way.
!Adentro!

And here is news of the Sing Sing DVD, which you can buy; the website has lyrics to “Viva mi patria Bolivia” in Spanish and English.

[? Does anyone know why, in Bolivia, the band always says “!adentro!” after the music starts and just before they start singing? One of course understands the meaning but I have not figured out what the origin of this is, and I always forget to ask.?]
Darn! I wish I would have been able to see this. I hope that someone else posts it eventually.
Here’s the currently up version, good, and with great photographs. The one I linked to earlier is gone.
But the current one is by a real Bolivian band, very authentic. !Adentro!
And here it is, with different video, of people dancing cuecas!

Apparently one just Googles the title, and currently allowed recordings and videos come up.
Bolivia is a great country. Maybe it should supplant Mexico as my favorite, I don’t know.
And here’s the Kory Huayras’ version:
