Steve James in his book "Roots and Blues Fingerstyle Guitar" writes "'Spanish Fandango' was derived from the influential guitar music of 18th century Spain, this waltz was quite popular with American guitarists of the 1800s, and numerous arrangements were published. It was published in 1860 by Henry Worral... 'Spanish Fandango' is one of the true parent pieces in American guitar music, and many recordings exist."
