We’re used to seeing some unusual things on the Got Talent franchise, but this act is possibly the most ingenious one you’ll see for many years.

The Brown Brothers, Gabriel and Nate, are not your usual contestants. They’re both U.S. Navy veterans (thanks for your service) but they are also both autistic. To help with communication, they’ve developed an incredible skill: singing impressions of other artists.

With this wild set-up, they ask the judges to pick from 500+ combinations of songs and artists for them to perform. Once they start singing, it’s equal parts wonder–when they sing like the actual artist–and laughs when they impersonate are Kermit the Frog and Donald Duck.

But they save the best for last–you have to watch their impression of Simon Cowell singing, “Someone You Loved”! Watch the full video below and please leave us a Facebook comment to let us know what you thought!
