Is Mieszko Kalita the Voice of the G Train?

An astute Greenpoint reader pointed out that the voice of the G train sounds remarkably like Community Board 1 Public Safety Chair and mascot Mieszko Kalita, above. I called Mieszko and he said "No, definitively no. I use the G train a few times a year to go to my daughters parent teacher conference and that's about it."

So Miezko is out, but could it be his long lost older cousin, Nieszko, right?
