The 4 PM signing will take place at the Lexington Avenue and 86th Street location. A listening party will begin at 3 PM. Currently confirmed to appear are Sondheim, Tony-winning orchestrator Jonathan Tunick, Tony Award winner Lin-Manuel Miranda, Tony Award nominee Celia Keenan-Bolger, Adam Grupper, Betsy Wolfe and Elizabeth Stanley.

As previously reported, the new concert cast recording of Merrily We Roll Along will be in stores July 10. The recording features new orchestrations by Jonathan Tunick and is the only album to include all the changes that Sondheim and librettist George Furth made in the decades following Merrily's initial 1981 Broadway run. It's also the first time that the post-1981 material is fully orchestrated for a large Broadway-style orchestra (Tunick did the original orchestrations, too).
