Shawn Mendes invited former One Direction singer Niall Horan to join him for a surprise duet of Horan's debut solo single This Town at London's O2 Arena this past weekend. A newly surfaced video of that performance has now drawn notable reactions from fans and enthusiasts.

Gushing on their performance, one fan declared:

"This Town is an inter generational classic"
