CNN’s diving into the David Letterman retirement story, the night before Dave’s final broadcast as host of CBS’s Late Show. Jake Tapper will host David Letterman Says Goodnight, on Tuesday, May 19 at 9 PM ET, looking at the end of a late-night career that spans two networks and three decades.

This is not to be confused with CBS’s special on Letterman’s retirement, which already has aired and which took a less newsy approach. Not that CNN’s special isn’t going to be a love-letter, which appears to be the case based on this morning’s announcement. Tapper will look back on Letterman’s tenure, examining how he redefined the talk-show genre and battled for the late-night crown against his NBC rival, Jay Leno. Tapper provides an in-depth look at Letterman’s career, including clips from Dave moments, as well as through interviews with his peers.

According to CNN, the list includes:

· Paul Shaffer, Letterman’s band leader and sidekick throughout his late-night career who says he had a “dream job, working for a dream boss who encouraged me to do what I wanted.”

· Jimmy Kimmel, the ultimate “Letterman Fanboy,” who jokes that he remembers more about “Late Night” than his own life and that the show was the “most formative thing in his life.”

· TBS late-night host Conan O’Brien, whose dream job was to become a writer on Letterman’s show after college in 1985 and who, in 1993, replaced Letterman on NBC’s “Late Night.” A virtual unknown when he started, Conan was truly honored that Dave paid an early visit to him as a guest on his new show.

· Seth Meyers, new to the talk show scene after an acclaimed career on Saturday Night Live, who took over the “Late Night” franchise in 2014. Meyers told Tapper that Letterman has “influenced the next generation.”

· Merrill Markoe, Letterman’s lead writer and longtime girlfriend, who engineered most of the original concepts for the show, including “Viewer Mail” and “Stupid Pet Tricks.” Throughout Markoe’s tenure with Letterman, she says, “he was in constant fear of cancellation.”

· Steve O’Donnell, who was with the Letterman show almost from the beginning and became head writer. O’Donnell calls his time at the show “the best, craziest job” he’s ever had. He and his writing team came up with many of the skits and helped craft the classic Top 10 list.

· Hal Gurnee, a late-night television veteran and Letterman’s longtime director, who became one of Dave’s favorite muses.

· Bill Carter, veteran New York Times reporter and author of The War for Late Night: When Leno Went Early and Television Went Crazy, who has covered the TV industry for more than 25 years and recalls Letterman’s unparalleled banter with late-night king Johnny Carson.
