Los Mockers were a popular 1960s rock band in Latin America that was part of the Uruguayan Invasion.

Their third single, "Captain Grey" / "Confusion" was released in mid- 1967, to boost sales of the album.

The record company proposed to re-record them on the condition that change their original name, but the group refused as there was no contract signed.

With little work and economic issues, plus internal conflicts among its members, vocalist Polo Pereira left and was quickly replaced by pianist and singer Carlos Franzeti.

On September 23 of 2006, forty years on from first recording, Mockers met in Valencia (Spain), with all their original members, except Freigeda Beto, who died in a traffic accident early in 1972 in Montevideo.
