One benefit of the hit TV series Riverdale shooting in Vancouver is that the production has infused over $60 million into the local economy. There's another benefit that may very well be priceless: surprise star appearances.

Much to the pleasure of fans, two Riverdale stars popped up on stage to perform at FVDED in the Park on July 7 in Surrey's Holland Park.

It was somewhat logical that Riverdale co-stars KJ Apa and Ashleigh Murray would join Norwegian DJ Kygo in a performance of his single "It Ain't Me", as both have musical connections.

Murray plays Josie McCoy, who is the lead singer of Josie and the Pussycats. Meanwhile, Apa had previously taken to the stage to perform the song with Kygo at Coachella in Indio, California, on April 20.

On stage in Surrey, Murray took on lead vocals (which were performed by Selena Gomez on the single) as Apa backed her up on the guitar.

Although Murray performs as part of her character's all-girl band on Riverdale, she noted on social media that it was first time performing live in front of a crowd of that size.

The good news is that New Zealand's Apa, who previously branded the city as boring, has found something here to enjoy beyond food and the gym.

FVDED in the Park, an all-ages showcase of electronic dance music, hip-hop, and R&B music billed as the largest urban music festival in Western Canada, ran from July 6 to 7.

Riverdale, which wrapped production on Season 2 in March, was renewed by the CW in April and just got into production for its third season. The series will continue shooting until April 19, which leaves plenty of time for future surprise appearances around town.

Season 3 of Riverdale will premiere on October 10.
