Rata de dos patas: Mexico’s famous insult song

For more than 25 years, Rata de dos patas has been one of Mexico’s most recognisable - and unusual - songs. A relentless string of insults, it was made famous by the singer Paquita la del Barrio.

Composer Manuel Eduardo Toscano recalls the moment in 2000 that convinced him the song was right for Paquita, and reveals how it almost never saw the light of day. He speaks to Helen Ledwick about the song's true inspiration and how it went on to become a huge hit.
