The headline above will link to a brief obit on Al Lewis over at NBC10.com
Lewis had a show on Pacifica's WBAI 99.50 FM here in New York City for years. He'd rant on politics, culture and prison reform (in which he was especially active). I recall first seeing him in the classic CAR 54, WHERE ARE YOU? television series and later in his most famous role as "Grandpa" Munster. Howard Stern fans will recall him from his frequent appearances on Stern's pre-Sirius program.
Rest in Peace, Mr. Lewis!
