The $19.50 Uncle Charley almost paid for two tickets to a play would be equal to just over $123 in 2020.
The title is based on the musical/movie The Sound of Music (1965) with music by Richard Rodgers, lyrics by Oscar Hammerstein II and book by Howard Lindsay and Russel Crouse. The original Broadway production of "The Sound of Music" opened at the Lunt-Fontanne Theatre on November 16, 1959, ran for 1443 performances and won (in a tie) the 1960 Tony Award for the Best Musical.
