The end of the road for KISS has been a long one.

But the classic band's ongoing "End of the Road World Tour" is due to conclude at the end of this year after it was first announced in 2018 and, at one point, scheduled to wrap in 2021. Now, eying their final show in December 2023, KISS rocker Gene Simmons said KISS is really calling it quits this time — while they're "on top."

It's just a matter of physics, he explained.

"At a certain point, Mother Nature takes over no matter what your plans are," Simmons tells the Australian news show The Sunday Project, as reported.

The KISS figurehead continues, "At a certain time, you've gotta have the dignity and pride but also the love and admiration of your fans to know when it's time to call it quits."

Comparing the endurance of KISS to that of an athlete, Simmons said the group he carries with longtime bandmate Paul Stanley doesn't want to overstay its welcome.

"We've all seen boxers that stay in the ring too long," the KISS bassist and co-vocalist adds, "and we've all seen bands that stay on the stage too long. So I'm still looking pretty damn good. But that's not the point. The point is the physical nature of what we do is gonna limit how long we do it."

KISS Quitting While the Quitting's Good

Simmons says, "We introduce ourselves with, 'You wanted the best, you got the best — the hottest band in the world.' I don't wanna be in one of those bands where the fans just say, Oh, you should have seen them back in 1804 when they were really rocking."

He surmises, "Right here, right now, either be a champion or get off the stage. So we're gonna quit while the quitting's good — while we're on top."
