Las Ketchup is a short-lived Spanish family pop girl group, founded by flamenco producer, Manuel 'Queco' Ruiz. The group is best known for the 2002 song, "The Ketchup Song" ("Aserejé"), a single that sold over 7 million copies. The group's first album sold over 12 million copies, but the second did not achieve the same success. Las Ketchup was originally discovered by the flamenco producer Manuel 'Queco' Ruiz, who signed them to his newly formed, independent Córdoba label Shaketown Music, that he ran together with Manuel Illán. In the summer of 2002 they had a major flamenco Europop fusion hit with "Aserejé" (released as "The Ketchup Song" in the UK and other countries), which reached the top of the charts in many countries, including: Spain, Portugal, Colombia, the UK, Italy, Greece, France, Finland, Turkey, Syria, Sweden, Norway, Belgium, the Netherlands, Philippines, Switzerland, Germany, Romania, and Australia. However, it failed to hit the Top 40 on the U.S. Billboard Hot 100. The title and part of the lyrics were in Spanish. The hit also had an accompanying dance. The second single was "Kusha Las Payas" and garnered moderate success. The group re-released "The Ketchup Song" later in the same year, with a new video, as a Christmas song. The group took an extended absence from the public eye to write songs for a new album and, during the same period, Pilar had a baby. In 2006, they were joined by Rocío, a fourth sister, and came back as a four girl group to represent Spain in the Eurovision Song Contest 2006. The girls have said themselves that Rocío has always been a member of Las Ketchup, but she wasn't in the photographs, videos, or performances because she was pregnant. They released their second album titled Un Blodymary. The album release was delayed until the beginning of 2006. They planned to release 1 million copies and their producer Queco, who also produced and wrote their worldwide single "Aserejé", indicated that the album displayed their original sound. Their first single from the album was also titled "Un Blodymary" for the Spanish entry in the Eurovision Song Contest 2006. The song finished 21st with 18 points.
