In 1991, just after leaving her stint as leading lady Christine in Broadway’s “Phantom of the Opera,” Helena’s Rebecca Luker received what she calls “a great blessing in my life.”

She was asked to join the cast of the musical version of “The Secret Garden,” with music by Lucy Simon (Carly’s sister) and lyrics by Pulitzer Prize-winner Marsha Norman, based on the classic children’s tale by Frances Hodgson Burnett.

“It was absolute heaven,” Luker says of playing Lily. “I was so excited to be originating a role. It was wonderful.”

Luker stayed with “The Secret Garden” for its nearly two-year run and went on to many memorable roles on the Broadway stage, including Tony Award nominations for “Show Boat,” “The Music Man” and “Mary Poppins.” And now, 22 years after “The Secret Garden” closed, she’s revisiting the role of Lily in a staged concert version of the musical.

Friends in Theater, which is producing the benefit for the Make-A-Wish Foundation, approached Luker in hopes of reuniting members of the original cast. Eleven-year-old Daisy Eagan became the youngest woman to win a Tony Award for her performance as Mary Lennox in the show; Luker played her aunt, Lily; and other cast members included Mandy Patinkin and John Cameron Mitchell, the latter of whom would later create “Hedwig and the Angry Inch.”

As it turns out, only Luker and one of the members of the ensemble of the original company of “The Secret Garden” are in it, with Simon and Eagan, now 36, hosting the evenings (one performance took place Jan. 11, and the second is Sunday at off-Broadway’s Lucille Lortel Theatre; both performances are sold out.)

Luker has fond memories of “The Secret Garden,” in which her character is a ghost.

“The only time I really had to relate to another actor was when I was in a couple of flashback scenes with the woman who played my sister,” Luker recalls. “I sang a duet with my son and husband, but because I was a ghost, I didn’t really interact with them.”

She’s enjoying revisiting the role of Lily.

“It’s more fun to sing now than 25 years ago,” Luker says. “It’s still difficult, but I’ve learned a thing or two in the past 25 years. I think I bring more to it vocally and dramatically.”

Reuniting with Eagan has been especially fun, Luker says.

“We have seen each other over the years, but we haven’t gotten together socially,” she says. “But we might now. She was 11, and now she’s 36 and has a 3-year-old son. I love Daisy. She’s a remarkable young woman.”

Luker is still hopeful that “Little Dancer,” a musical she has been attached to, will get produced, and in the meantime she’s auditioning and doing concerts with symphonies around the country.

Her husband, Danny Burstein, is starring as Tevye in the acclaimed Broadway revival of “Fiddler on the Roof,” and the two recently guest starred together in a memorable episode of “Law & Order: SVU.” In it, they played the parents of a transgender youngster killed in an accident after being bullied.

“We loved the script,” says Luker, who, with Burstein, champions LGBTQ rights. “Danny got the role first, and I called my agent and said, ‘My husband just got this part, and I need to be seen for the wife.’ The producers got together and just gave me the part. It was lovely, and I have Danny to thank.”

It was a particularly dramatic and emotional episode of “SVU,” and it required some intense shooting.

“We literally cried and yelled and screamed for eight days,” Luker says. “Everyone we know disagreed with the judge’s decision in the show, but the writers made their point. Bigotry and picking on someone because of their sexuality is a terrible thing to do.”
