Fish starts toying with his "YEAH" sample during Trey's crooning at the end of the song proper to let him know he's ready to jam (the sample also makes an appearance or two later on).

This is the band fully leaning into one of their most reliable "jam vehicles" and sounding like one organism. There are multiple parts that make the listening wonder, "Who's playing what?" Page rocks his synth to give this jam that quintessential 2021 sound, he and Mike have some excellent interplay around 14:00 before Trey takes everyone back into the chorus.
