Everyone's got a go-to karaoke song, whether it be something as crowd-pleasing as 'Bohemian Rhapsody', or even something as recent as 'Shallow'.

Either way, if you're looking for a low-effort karaoke song, there's one good track that works for everyone. 'Tequila', by the Champs. It's got one line, and that's all you need.

In fact, a viral video from a few years ago did the rounds of a man singing it at a karaoke bar in the US that was... well, yeah. Take a look.

As you may or may not have clocked, the video was by a comedian named Andy Rowell. The clip went viral across Vine (RIP) and had close to 4 million views on YouTube, all of it with Rowell standing awkwardly and waiting for the song to finish.

Anyway, this week's edition of 'America's Got Talent' saw Andy Rowell on stage, singing a karaoke act that included - you guessed it - 'Tequila'. While you might think that this kind of internet comedy wouldn't go over with the likes of Simon Cowell or Howie Mandel, the reaction was genuinely surprising.

Rowell's act made it through to the end with no buzzer, and had basically won over the judges - and the crowd - with its nebulous anti-comedy. Or maybe it's just a good song and people fancied a quick blast of it.

Who knows. Here's his moment on 'America's Got Talent'.
