IN: Rowan & Martin's Laugh-In (often simply referred to as Laugh-In) is an American sketch comedy television program that ran for 140 episodes from January 22, 1968, to March 12, 1973, on the NBC television network. It was hosted by comedians Dan Rowan and Dick Martin. Laugh-In originally aired as a one-time special on September 9, 1967, and was such a success that it was brought back as a series, replacing The Man from U.N.C.L.E. on Mondays at 8 pm (ET). The title of the show was a play on the "love-ins" or "be-ins" of the 1960s hippie culture, terms that were, in turn, derived from "sit-ins", common in protests associated with civil rights and antiwar demonstrations of the time.

The 1970-71 season brought new additions to the cast include tall, lanky, sad-eyed Dennis Allen, who alternately played quietly zany characters and straight man for anybody's jokes; comic actress Ann Elder, who also contributed to scripts, tap dancer Barbara Sharma, and Johnny Brown.  Arte Johnson, who created many memorable characters, insisted on star billing, apart from the rest of the cast. The producer mollified him, but had announcer Gary Owens read Johnson's credit as a separate sentence: "Starring Dan Rowan and Dick Martin! And Arte Johnson! With Ruth Buzzi ..." This maneuver gave Johnson star billing, but made it sound like he was still part of the ensemble cast. Johnson left the show after the 1970-71 season. Henry Gibson also departed after the 1970-71 season. Johnson and he were replaced by former Hogan's Heroes stars Richard Dawson and Larry Hovis, both of whom had appeared occasionally in the first season. However, the loss of Johnson's many popular characters caused ratings to drop further.  After winning the Academy Award for Best Supporting Actress in Cactus Flower, Goldie Hawn made a guest appearance in the third episode of the fourth season. She began the episode as an arrogant snob of an actress; however, a bucket of water thrown at her transformed her back to her giggling dumb blonde persona.  The show celebrated its 100th episode during the 1971-72 season, with Carne, Worley, Johnson, Gibson, Graves, and Tiny Tim all returning for the festivities. John Wayne was on hand for his first cameo appearance since 1968.

input: The Clive Davis's pre-Grammy party that Houston was expected to attend, which featured many of the biggest names in music and movies, went on as scheduled although it was quickly turned into a tribute to Houston. Davis spoke about Houston's death at the evening's start:  By now you have all learned of the unspeakably tragic news of our beloved Whitney's passing. I don't have to mask my emotion in front of a room full of so many dear friends. I am personally devastated by the loss of someone who has meant so much to me for so many years. Whitney was so full of life. She was so looking forward to tonight even though she wasn't scheduled to perform. Whitney was a beautiful person and a talent beyond compare. She graced this stage with her regal presence and gave so many memorable performances here over the years. Simply put, Whitney would have wanted the music to go on and her family asked that we carry on.  Tony Bennett spoke of Houston's death before performing at Davis's party. He said, "First, it was Michael Jackson, then Amy Winehouse, now, the magnificent Whitney Houston." Bennett sang "How Do You Keep the Music Playing?" and said of Houston, "When I first heard her, I called Clive Davis and said, 'You finally found the greatest singer I've ever heard in my life.'"  Some celebrities opposed Davis' decision to continue on the party while a police investigation was being conducted in Houston's hotel room and her body was still in the building. Chaka Khan, in an interview with CNN's Piers Morgan on February 13, 2012, shared that she felt the party should have been canceled, saying: "I thought that was complete insanity. And knowing Whitney I don't believe that she would have said 'the show must go on.' She's the kind of woman that would've said 'Stop everything! Un-unh. I'm not going to be there.' [...] I don't know what could motivate a person to have a party in a building where the person whose life he had influenced so enormously and whose life had been affected by hers. They were like... I don't understand how that party went on." Sharon Osbourne condemned the Davis party, declaring: "I think it was disgraceful that the party went on. I don't want to be in a hotel room when there's someone you admire who's tragically lost their life four floors up. I'm not interested in being in that environment and I think when you grieve someone, you do it privately, you do it with people who understand you. I thought it was so wrong."
