I stumbled on this a few days ago, Charlie Rose interviewing Warner Wolf and Glenn Brenner in 1984 on CBS Nightwatch:

After Wolf, the native Washingtonian moved onto New York in the 1970s, Brenner eventually replaced Wolf at Channel 9 (then WDVM, now WUSA). After Brenner died, Wolf was brought back to D.C. where he flopped as Brenner’s successor.

Not as funny as I would have hoped, but still interesting.
