was the featured soloist in a program of theatre music given by the Oratorio Society of New York. In 1994, she provided both her acting and singing skills to the animated film version of Thumbelina, as Thumbelina's mother which featured music by Barry Manilow. That same year she was inducted into the American Theatre Hall of Fame. In November 1997, Cook celebrated her 70th birthday by giving a concert at Albert Hall in London with the Royal Philharmonic Orchestra, joined by performers including Elaine Stritch and Maria Friedman. The Times reviewer noted: "The world is usually divided into actresses who try to sing and singers who try to act. Cook is one of the few performers who manage to combine the best of both traditions, as she reminded us in 'It Might as Well be Spring' – and, at the close, in her encore of Bock and Harnick's 'Ice Cream'." In 2000, she was one of the only American performers chosen to perform at the Sydney 2000 Olympic Arts Festival in the Sydney Opera House. Also in 2000, she was joined by Lillias White, Malcolm Gets, and Debbie Gravitte on the studio cast recording of Jimmy McHugh's Lucky in the Rain. In February 2001, Cook returned to Carnegie Hall to perform Barbara Cook Sings Mostly Sondheim which was recorded live and released on CD. Critically acclaimed from the start, Cook then took the concert to the West End Lyric Theatre in 2001. She garnered two Olivier Award nominations for Best Entertainment and Best Actress in a Musical for the concert. She went on to perform Sings Mostly Sondheim at Lincoln Center for a sold-out fourteen-week run from December 2001 to January 2002, and again in June 2002 to August 2002. She was nominated for a Tony Award for Best Theatrical Event. She took the show on a National tour throughout major cities in the United States. DRG filmed the stage production during a performance at the Pepsico Theatre, SUNY Purchase, New York, on October 11, 2002 and it was released on DVD on the DRG/Koch Entertainment label. In June and August 2002 Cook performed Sings Mostly Sondheim at the Terrace Theater, Kennedy Center as part of the Sondheim Celebration. In 2004 she performed two limited engagement concert series at the Vivian Beaumont and Mitzi Newhouse theaters at Lincoln Center, "Barbara Cook's Broadway!", with Harper as her musical director/arranger.
