The three singers sat in a circle harmonizing on "Minnie the Moocher's Wedding Day" as though 35 years hadn't passed.
As they sang, Tim Sparks played one wrong note on guitar, and after "Minnie" was done, fellow guitarist Tom Lieberman corrected him.
"It's spooky how fast all that music comes back," Sparks said.
"Ninety-five percent comes back," Lieberman observed. "It's the other 5 percent that makes it good."
Rio Nido, the Twin Cities trio that made retro vocal jazz cool in the late 1970s and '80s, is rehearsing for its first bona fide Twin Cities club gig in three decades, set for Friday at the Dakota in Minneapolis.
"This is a project from [our] youth — we want to see what everybody brings 30 years later," said singer Prudence Johnson during a recent rehearsal in her Minneapolis living room.
The reunion came together because individuals in Rio Nido were asked to play a benefit for Friends of the Headwaters this past summer in Park Rapids, Minn., and they agreed to do it together — their first performance since a one-off a decade ago in St. Paul.
"It was a really great show," Sparks said, "so we approached the Dakota."
