Garry Shandling died a year ago today at the age of 66.

A consummate comic’s comic and a television pioneer not once but twice, Shandling left a permanent legacy for us to behold and celebrate.

Tonight, SiriusXM will pay tribute to the late great comedian with an audio documentary, “Garry Shandling — A Life in Comedy.”

It premieres at 8 p.m. Eastern tonight on SiriusXM Comedy Greats (Ch. 94). Hosted by Ron Bennington, with commentary and insight from Judd Apatow, Jeffrey Tambor, Kevin Nealon, Janeane Garofalo, Artie Lange, Pete Holmes, Kathleen Madigan, Alan Zweibel, and Andy Kindler.
