The venue billed the concert as follows: "Before Eli Stone, there was Sweeney Todd, before 'Titanic,' there was Lend Me a Tenor, before 'First Wives Club,' there was Assassins, before 'Alias,' there was Arcadia and before 'Legally Blonde,' there was Damn Yankees. The New York stage is thrilled to welcome back Victor Garber as he makes his cabaret debut."
