string of songs ... Half of the songs come from Company and Follies; most of the other Sondheim musicals are represented, including the lesser-known Passion and Road Show". For the 2014 film adaptation of Into the Woods, Sondheim wrote the new song "She'll Be Back", sung by The Witch, which was cut from the film. In February 2012, it was announced that Sondheim would collaborate on a new musical with David Ives, and he had "about 20–30 minutes of the musical completed". The show, tentatively called All Together Now, was assumed to follow the format of Merrily We Roll Along. Sondheim described the project as "two people and what goes into their relationship ... We'll write for a couple of months, then have a workshop. It seemed experimental and fresh 20 years ago. I have a feeling it may not be experimental and fresh anymore". On October 11, 2014, it was confirmed the Sondheim and Ives musical would be based on two Luis Buñuel films (The Exterminating Angel and The Discreet Charm of the Bourgeoisie) and would open (in previews) at the Public Theater in 2017. In August 2016, a reading for the musical was held at the Public Theater, and it was reported that only the first act was finished, which cast doubt on the speculated 2017 start of previews. There was a workshop in November 2016, with the participation of Matthew Morrison, Shuler Hensley, Heidi Blickenstaff, Sierra Boggess, Gabriel Ebert, Sarah Stiles, Michael Cerveris, and Jennifer Simard. The working title was reported to be Buñuel by the New York Post and other outlets, but Sondheim later clarified that they still had no title. In June 2019, the Public Theatre denied reports that it would be part of its 2019–20 season, as it was still in development, but would be produced "when it is ready". On April 27, 2021, it was reported that the musical was no longer in development. On The Late Show with Stephen Colbert on September 15, 2021, Sondheim announced he was working on a new musical called Square One in collaboration with Ives. The same day, Nathan Lane revealed that he and Bernadette Peters were involved in a reading of this new work. In Sondheim's final interview before his death, he confirmed that Square One was adapted from the Buñuel films. Sondheim makes a posthumous cameo appearance as himself in the 2022 Netflix film Glass
