J. Lo, Ricky Martin On Charity Single Unveiled At White House

'El Ultimo Adios' also features Gloria Estefan, Jon Secada, Christina Aguilera.

Gloria Estefan and Jon Secada premiered "El Ultimo Adios" — a song the two recorded with a virtual supergroup of Latin music luminaries including Ricky Martin and Jennifer Lopez — at the White House on Friday, the same day the charity single was sent to radio stations.

The song, also recorded in English and titled "The Last Goodbye," will raise money for the American Red Cross and the United Way to assist families of victims of the September 11 attacks on the World Trade Center and Pentagon, according to a publicist for Estefan Enterprises in Miami.

Producer Emilio Estefan Jr. put together the lineup, which featured more than 70 artists including Shakira, Christina Aguilera, José Feliciano and Tito Puente Jr. While basic tracks were recorded in Miami, most of the artists added their vocals from studios in New York; Los Angeles; Madrid, Spain; Mexico City; San Juan, Puerto Rico; and Corpus Christi, Texas.

"In the four minutes of this song, we are sending a message of unity and hope that will last a lifetime," Emilio Estefan Jr. said in a statement. "Different music genres were represented, [and] all the artists sang together to inspire faith and hope to all affected by this tragedy."

Gloria Estefan and Secada, who co-wrote "El Ultimo Adios" with Peruvian singer/songwriter Gian Marco, performed the song at a White House event celebrating Hispanic Heritage Month. They were joined by more than a dozen artists including jazz trumpeter Arturo Sandoval. A CD with both the English- and Spanish-language versions will be released in November, according to the publicist.
