I heard this played by John Williams on the Places Between CD. The CD is a collaboration between the two Johns...Williams and Etheridge, but JW plays this as a solo on the CD. I am very reliably informed that Totumo = Gourd tree. Gourd is good for making Maracas, a percussion instrument and that Guarenas = small city near Caracas. Thank you Marie. This is a very rough version all the same!!
