In The Music Man, Jackman and Sutton Foster shine as Harold Hill and Marian, respectively. The musical follows Harold, a con man, who poses as a boys' band organizer and leader who sells band instruments to naive townspeople, promising to train members of a new band.

Behind the scenes, Harold (who has no music skills) plans to skip town, but is caught up in wooing the prim librarian and piano teacher Marian.

Speaking with PEOPLE during opening night, Furness, 66, chatted about how she helped set up Jackman for success before the first show.

"The day of, like today, it's usually a very noisy household at our place with everything going on," she said. "But I keep it very quiet, very calm so it's like the calm before the storm."

When asked how she convinces 21-year-old son Oscar and 16-year-old daughter Ava, whom she adopted with Jackman, to stay cool, Furness joked, "Ice cream, just keep feeding them."

The Music Man is now playing on Broadway in New York City.
