I don't find any reference for Ronnie Gilbert singing ERES ALTA Y DELGADA. Please let us know what record label, catalog number, title
if you find it.

However, CYNTHIA GOODING recorded it on her 10" ELEKTRA album:
Turkish and Spanish Folksongs: Cynthia Gooding
Elektra EKLP 6 (Mono)
This was reissued on the 12" LP ELEKTRA EKL 128 Cynthia Gooding sings Spanish, Mexican and Turkish folk songs

Best wishes, Thomas.
