I loved the song "El Condor Pasa" when I first heard it on
a Simon and Garfunkel record many years ago (it was, in fact,
one of the first L.P.'s I bought, having outgrown 45's)
I didn't know that he'd borrowed the song from Urubamba,
a Peruvian street band that had been playing traditional Andean
music in New York in those days until many years later.   (are they still around?
there are lots of other Andean groups out there, Inca Son who play around Boston
spring to mind - but is there still an Urubamba?)
