To walk into the Hideaway is to enter a place that seems frozen in time, where the dozen or so seats around the piano are packed with your grandparents' friends, decked out in chunky jewelry and tilted fedora hats. Ostensibly, they're here to listen to Mark Dew play — he's here Wednesday, Friday, Saturday and Sunday nights — but you're just as likely to hear one of those old-timers sitting around the piano trill Charlie Rich's "The Most Beautiful Girl." And when Dew finally has his turn at the mic, he'll say something humble, like, "I apologize; it should have been in the key of F." No matter. Dew is the conductor of this time-traveling train, and everyone's on board. Dew, who is blind, has been the piano man here for nearly a quarter-century and jokes that the best part about working here is, well, getting paid. He marvels at the younger set trickling in and its knowledge of the Cash and Sinatra songbooks: "The more the crowd gets into it, the more I play," Dew says. And that's enough to keep him around. "I'm not quite ready to be out to pasture," he says. "Yet."
