Originally known as The Latin Blues Band featuring Luis Aviles, for their third album they were renamed to Los Astronautas or – in English – the Moon People.
Their best known track was originally called "(I'll Be A) Happy Man", released in 1968 on the Latin Blues Band's "Take A Trip Pussycat" album. It was later re-released on the Moon People album "Land Of Love" as "The Happy Soul". Subsequently, "The Happy Soul" was edited and overdubbed with organ solos by Dave "Baby" Cortez and released as "Happy Soul (With A Hook)". In 1969 yet another Moon People re-edit of this track titled "Hippy, Skippy, Moon Strut (Opus #1)" was released on Roulette. The Christina Aguilera song "Ain't No Other Man" produced by DJ Premier uses samples from "Hippy, Skippy, Moon Strut".
