Que Viva Chango is pure son cubano. Viva Yemaya is also son. She had several songs that used the same melody/chords. Also Que Viva Fidel.
She lived very close to me in Buenavista (across from my best friends house near 42 y 66). I only met her though when she was very old and really didn't discuss much "music" when I would see her.
