May 29 (UPI) -- Niall Horan honored the victims of last week's deadly attack in Manchester, England, on Monday's episode of Today.
"Before I start, I would like to dedicate [the song] to the people who lost their lives in Manchester last week. It was a very sad thing, so I just, it's the least I can do is dedicate this song," he said during his appearance.
Horan also sang his single "Slow Hands" and performed his new song "On the Loose" for the first time on TV. Hundreds of fans waited overnight in the rain to see the singer take the stage in New York City.
"Thank you for waiting all night for me, really appreciate it," Horan tweeted Monday morning. "Thank you all. I understand you all must be freezing and soaked through."
"Great time on @TODAYshow," he later added. "Thank you for having me and seriously thank you for coming out in your thousands, I really felt the love out there."
Horan is expected to release his debut solo album this year. He came to fame with the British boy band One Direction, which has been on an indefinite hiatus since December 2015. The star said last week he hopes the group will reunite in "the next few years."
