For Scott Ian and his son, Revel, it was a sweet “like father, like son” moment when Revel joined the Foo Fighters on stage at the Bourbon & Beyond festival to play guitar on “Everlong.”

Ian shared video of the moment below along with the caption, “There goes my hero! Proudest dad moment ever? How about when your son gets to join his favorite band on stage to play ‘Everlong’ in front of 40,000 people and NAILS IT! Thank you Dave, Taylor, Pat, Nate, Chris, Rami, Gus, Kerwin, Sean, Patrick, Simone and everyone else on the Foo crew for being the best!!!”

Added bonus for this cool moment is when Dave Grohl instructs Ian to be his son’s guitar tech.
