Has to be Sylvester, aka
Sly.
He was an older black man, supposedly a Vietnam vet, who spent pretty much every day/night roaming some of the city's more popular nightlife/restaurant areas. He would panhandle, but usually wasn't too aggressive about it. He'd stop and talk to you, befriend you, and then ask you for money. There's all sorts of urban legends about the guy. He clearly had a mental handicap of some kind, and you never really knew on a given night whether he'd be friendly and lucid or whether he'd start swearing at you if you didn't give him some money or a cigarette. Most bars wouldn't let him in, but it wasn't uncommon to see him standing out front, shooting the #### with the bouncer at your favorite bar. If you spent any evening in or around either the Elmwood Village or Allentown in the past 15 years, you know exactly who he is even if you didn't know his name.
He died just a few weeks ago, early March. Buffalo News wrote up a nice obituary for him. Guy's a legend.
