For the second time in a year, Corey Taylor's son Griffin joined his dad onstage with Stone Sour to sing "Song #3" from the band's Hydrograd album. The performance took place Wednesday night (July 11) at Coliseu dos Recreios in Lisbon, Portugal.

The elder Taylor beamed as his son, whose matching haircut made him look like a mini-me, took the stage. Before the band started the tune, Taylor announced, "I've got something very special for you right now … We've only ever done this one other time, and it was one of the best fucking nights of my life. So I wanna invite to the stage my son, Griffin Taylor. Griffin's gonna help us out on this next song. And we're gonna do our very best, aren't we?"

Stone Sour's frontman stood back and smiled while his son stood on a platform and sang lead vocals for the number. Griffin previously sang the song with the band last year at the PNC Bank Arts Center in New Jersey.

Speaking last year with Cincinnati radio station WEBN, Taylor recalled, "I'm thinking about it now and I'm gettin' goosebumps. He handled it so well, he was so into it and just sang his ass off. It was so rad! And we were all so into it that we were missing parts — we just kept making mistakes. It was, like, 'The kid's making us look good. Jeez.' So it was pretty rad, man. Just being able to see him do that, I've never felt that kind of pride in my life."
