A boy with autism was moved to tears by Coldplay's concert performance of "Fix You," and a video of that moment has evoked equally emotional reactions among its millions of viewers — including the band itself.
In a video YouTube user Luis Vazquez posted to the video-sharing site last Tuesday, the dad shows his young son skipping his way into the Coldplay show on April 16 in Mexico City. The video cuts to Vazquez and his son in the crowd, listening to the last two minutes of the band's live performance of "Fix You." The stirring 2005 hit's lyrics offer hope and help to someone who's enduring sadness and adversity.
Vazquez's son cries, wipes his eyes, covers his face and jumps up and down with his dad as the music swells. Seeing this, the dad kisses his son's cheek as Coldplay's lead singer Chris Martin sings, "See it stream / down your face / when you lose something / you cannot replace."
The song and video conclude with Vazquez wrapping his arms around his son as the audience at Foro Sol stadium sings the coda of "Lights will guide you home / And ignite your bones / And I will try to fix you."
The YouTube video has gone viral, with more than 2 million views as of Tuesday afternoon.
A translation of the video's caption reveals Vazquez uploaded it because it was something he and his wife wanted to share with the world. Vazquez's follow-up comment, in English, encourages viewers to "keep looking for sharing [these] kind of things that make us understand there is still a chance for having a better place for them! #autismspeak."

Coldplay responded Friday on Twitter, where the band has almost 17 million followers. Linking to Vazquez's emotional video, Coldplay's tweet greeted Luis and his "hijo hermoso" (beautiful boy) in Spanish, adding in English, "This kind of thing makes it all worthwhile."
That tweet had been liked almost 20,000 times and retweeted more than 13,000 times as of Tuesday afternoon. But perhaps Vazquez, himself, appreciated it the most, as a Twitter user by that name thanked band members for their shout-out and support.
Many other fans worldwide were deeply moved by the display. Among those commenting on one of Vazquez's concert photos on Instagram, one user called the video "the most beautiful thing I've ever seen in a very long time." Twitter users expressed similar praise and emotion.
Thankfully, Vazquez's son didn't cry during the whole Coldplay concert. He smiles and jumps during the band's performance of "A Sky Full of Stars," which, in the introduction of the video that went viral, he tells his dad is his favorite song.
Saturday on Instagram, Vazquez posted a sweet photo of his son in front of a microphone.
A partial translation of the Spanish caption thanks fans for their "incredible" messages, and includes the hashtags #autismrocks and #vivacoldplay. Vazquez asserts he's not done advocating for people with autism, adding, "It's not over until it's over."
