I recently acquired a Luis Sagi Vela record without a label, but it
contains various songs from zarzuelas. One track struck a chord with me
and I don't know the name of it. The opening line is, "En una noche
oscura de terrible tempestad."

I eventually bought the Vela CD "Grandes de Zarzuela" and the same aria
is track# 8 on that CD, but the disc list it as "Ramona" (which I know
is incorrect). I'd always heard this tune as a folk tune
called "Jinetes en el Cielo." Is this the correct zarzuela it is from?
Some search on the internet revealed a few hits listing the song as "La
ronda del vaquero." Any information provided would be greatly
appreciated.

Sincerest thanks,
Julian
