Of course, Jonas Brothers' fans in North America and elsewhere around the world are eager to see Joe, Nick and Kevin make it to their neck of the woods.
For now, we'll have to watch the JoBros live from their other concert dates.
Nick tweeted after the show: "Buenos aires you were awesome. Thanks for a great night."
As for the fan mania, the Jonas Brothers saw first-hand that fans are still head-over-heels for them, as seen in the video below from their sound check in Cordoba.
The official JoBros Twitter account wrote: "Reliving the moment from yesterday's insane sound check in Cordoba!"
It appears the measly rope that was to hold them back was no match for the Jonas Brothers fans' love!
