Been watching old episodes of the Dick Cavett show from the 1970s. If Colbert ever returns to tv talk shows, this format would suit him well. Both hosts are knowledgeable, genial, and quick witted.

No short five minute interviews, no desk to sit behind, no plugging your latest product — just a nice roundtable of articulate guests. Letting people speak and interact rather than the host talking over them or performing skits. Maybe lose the intro stand-up routine. Definitely include a live band as was common during this era.

I do wonder if alcohol or other substances were allowed in the green room for this show. The guests seem far more relaxed, open, and honest.
