Tren De Carga - Freight Train
Los Cinco Latinos
I wasn't able to find English language information online for Los Cinco Latinos.
They appear to be a pop group from Argentina who formed in 1957 and continued to entertain fans for at least the next several decades. Their wiki page discography indicates this LP was their third release.
I couldn't find an example of this cover online. The album has a nice cross-over vibe from 50s doo-wop to 60s light pop.
