The album Baro Love, by the band Lolo Lovina, has a track, Chiori Rromani. The liner notes say, "Anthem of Rroma held in concentration camps during 'O Porrajmos', or the holocaust of WWII." All the references I found on the web to Chiori Rromani trace back to this CD. The track is on Youtube at https://www.youtube.com/watch?v=c-TXIJtPEOQ
