After a declining and dissapointing change of At the Circus, their first work at MGM, the Marx Brothers seem to get back on the right truck in Go West in many ways. On the top sequence, Chico and Harpo trap Groucho at the train station: the two get the ticket to ride (as a result of Chico's skillful yell, "Nine dollars change, please!") and go to the west, while Groucho goes broke. Compared to At the Circus, laughing spots are more successfully and equally placed over the whole plot.
Also, in spite of the setting of the story, in the late 19th century, the Brothers highlight themselves with individual musical performances: Chico with his unique "shooting keys" of piano at the bar, Harpo with incredibly perfect harp playing at the native American's village (*Harpo actually transforms a mysterious outdoor object with strings into a harp!), and Groucho with backing vocals in two songs (*not his complete solo performance, but still good enough). Your 80 minutes will fly much faster than you expect if you watch this Go West!
