they listed some stuff that they did in the past production on Playbill. here's what they listed:
"Why We Like Spelling," cut from Spelling Bee, made an appearance at the end of Act One of Make Me a Song, with the cast in full middle-school drag. Act Two opened with a "suite" from Falsettos, including "Four Jews in Room Bitching," "A Tight-Knit Family," "Trina's Song," "March of the Falsettos," "The Games I Play," "The Baseball Game," "Something Bad," "Holding to the Ground" and "Unlikely Lovers."
Make Me a Song is not comprised of the "greatest hits" of William Finn, however. That idea didn't interest Ruggiero.
"Dear Reader (or, How Critics Kill Art)," a vocally ambitious exchange between an author and a critical consumer of her book, was a discovery for many listeners. "How Marvin Eats His Breakfast," from In Trousers, was included, and so was I Have Found, from Finn's take on Kaufman and Ferber's The Royal Family, an unproduced musical.
"Hitchhiking Across America" (sung by Cassidy) is an orphaned song from a show that was never completed. It surfaced in the revue.
Make Me a Song is not a chronological look at Finn's output over the years, and doesn't address Finn's shows in sections (except for Falsettos).
