Anyway, who was it who filmed it?
Did Parker say, "You can film whatever you want once the curtains fallen." and they took it literally.
CBS cameras had been there on behalf of Elvis' old TV "buddy" Ed Sullivan filming just 3 days before Elvis opened.
Two [Streisand] shows were recorded in Las Vegas ...
Ed Sullivan brought his cameras to tape a special segment with Barbra for his CBS TV show. Sullivan taped his part in front of the live audience. He introduced Barbra; she sang a medley of songs from Hello, Dolly!; then Sullivan came back on stage and congratulated Streisand. Ed Sullivan and the Dolly medley were shown September 28, 1969 on the opening show of his 23rd season. [A clip of Barbra singing “On A Clear Day” was shown on 1970's Entertainer of the Year Awards, too.]
Under the supervision of Sullivan's executive producer Bob Precht, Barbra's entire Vegas show was taped for a possible one-hour television special for the 1970 television season. She performed for the cameras and an invited audience of Las Vegas entertainers at 2:15 a.m. on Monday, July 28th.[ - This is the show Elvis attended!]
Precht told the press that he turned over the tapes to Barbra's manager, Marty Erlichman, who would seek a television deal for the footage.
The potential Streisand television special was shelved and never released.
In 1973, Marty Erlichman offered a possible explanation for the abandoned show: “The reason we didn't do any special for CBS for a long time was because of my running battle with Mike Dann,” Erlichman explained about Dann—who was senior vice president in charge of programming at CBS. “He never believed in Barbra as a talent. His idea for her was to put her in a special with Dick Van Dyke and Andy Griffith ... The last special we did was Central Park and it was right before her film career took off. We had it in the can and Mike Dann scheduled it to air on Sept. 12, 1968. Funny Girl was set to open on Sept. 18, 1968 and I begged him to air the special after the movie opened because it would be a more important event for CBS and Barbra. He wouldn't do it and I swore we wouldn't do anything for CBS until Mike Dann was out.
Fans have been patiently waiting to see Streisand Live at the International Hotel for years. Audio of Barbra's closing number (“When You Gotta Go / Wee Small Hours of the Morning”) was included on Streisand's box set, Just For the Record. And on her 2016 concert tour, footage from the show was used in the opening montage.
