On July 23, 2017, Groff performed in a one-night only symphonic concert production of "Sondheim on Sondheim" at the Hollywood Bowl. From January 20 to January 22, 2018, Groff starred as the titular character in the Off-Broadway production of "The Bobby Darin Story", a three-day concert and biographical retelling of the life of 1950s singing icon Bobby Darin, presented as part of the Lyrics & Lyricists series at 92nd Street Y and directed by Alex Timbers. The production was met with great critical reception, with Michael Ridel writing in the "New York Post" that Groff "moves with the ease and slyness of Darin".
