Nathan Sykes is a huge Pokémon fan.
During his performance at the PEOPLE Now Concert Series Presented by Toyota Music on Thursday, PEOPLE Now host Jeremy Parsons asked the singer why he chose to cover the Pokémon theme song, which he shared on Twitter Sunday.
“I grew up playing Pokémon, and everyone’s gone Pokémon crazy all over again – and my little nostalgia casts has never been happier,” explained Sykes. “It really is amazing that we can kind of relive the glory days of being young.”

He added with a laugh: “I say that like I’m 300 years old. I’m 23. Do you know what I mean? But then like younger kids who haven’t played Pokémon like we have, like play Pokémon for the first time, and just being obsessed with it – it’s just incredible.”
As for how many pocket monsters he’s caught so far? Sykes revealed he’s unsure.
“You know what I’ve had like no Internet for like the last three weeks,” he explained. “It’s like broken my heart because I’ve been out of the Pokémon game.”

Parsons then turned to the crowd and pointed out a kid in a Pikachu costume, who joined him and Sykes on-stage. And before heading back to the audience, the young Pokémon fan did a little dancing as Sykes sang the Pokémon theme song.
Sykes’ PEOPLE Now Concert Series Presented by Toyota Music performance on Thursday will be followed by Beyoncé protégées Chloe x Halle on Aug. 11 and Austin and Ally star Laura Marano on Aug. 18.
The performances will be streamed on PEOPLE.com and other Time Inc. digital platforms at 4 p.m. ET.
