Can we talk about “Pony” for a minute? Try to name a sexier song that you’ve heard in more public places. Since its unforgettable splashdown in the summer of 1996, Ginuwine’s everlasting slow jam has continuously made its presence felt inside nightclubs, strip clubs, shopping malls and wedding receptions — which makes it the freakiest song you’ve routinely danced to in the presence of other people’s grandmas.

According to Ginuwine, those grandmas have good taste. “They don’t even care,” he says. “They get up and dance, too!”

And although the District-born R & B singer is still proud of “Pony” for its elasticity and durability, he says that he’d rather be remembered for “Differences,” a gorgeous, midtempo fidelity pledge from 2001 that still gets plenty of wedding spins too. “It’s a song that I wrote when I was going through a lot of pain and sorrow with my mom and my dad passing, and really being out there, wild, not know which way to go,” Ginuwine says. “I wrote it for my wife — my now-ex-wife — and my daughter.”

That makes perfect sense. “Pony” is about a moment. “Differences” is about a life. One song is hot and outrageous. The other is warm and contemplative. And when you hear Ginuwine sing them both in concert — the one place where he’s actually thinking about his legacy in real time — you have the opportunity to measure a song that has spanned vast distances against one that comes from the singer’s deepest depths. Year after year, both somehow sound bigger.

Show: Feb. 16 at 8 p.m. with Tyrese, Avant, 112 and Next at EagleBank Arena, 4500 Patriot Circle, Fairfax. $59-$125
