In 1970 Menotti made the difficult decision to end his lengthy romantic relationship with Samuel Barber. Barber had battled depression and alcoholism following the harsh critical reaction to his 1966 opera
Antony and Cleopatra which had a negative impact on his creative productivity and his relationship with Menotti.' While there, he jokingly stated his Scottish neighbors referred to him as "Mr McNotti". In 1974, he adopted
Francis "Chip" Phelan, an American actor and figure skater he had known since the early 1960s. Chip, and later his wife, lived with Menotti at Yester House. The first of these was the cantata in nine parts for soloists, chorus and orchestra, "Landscapes and Remembrances," which premiered on May 8 in a performance by the
Bel Canto Chorus and
Milwaukee Symphony in Milwaukee. In 1977 Menotti founded
Spoleto Festival USA, a companion festival to his Spoleto Festival (the other of its Two Worlds), in
Charleston, South Carolina. For three weeks each summer, Spoleto is visited by nearly a half-million people. These festivals were intended to bring opera to a popular audience and helped launch the careers of such artists as singer
Shirley Verrett and choreographers
Paul Taylor and
Twyla Tharp. In 1986, he extended the concept to a Spoleto Festival in
Melbourne, Australia. Menotti was the artistic director during the period of 1986–88, but after three festivals there, he decided to withdraw – and took the naming rights with him. The Melbourne Spoleto Festival has now become the
Melbourne International Arts Festival. Menotti left Spoleto USA in 1993 to take the helm of the
Rome Opera. In spite of these festival's claims on Menotti's time, which included directing plays as well as operas, he maintained an active artistic career. Many of his later operas are directed towards children, both as subjects and as performers, including
The Egg (1976),
The Trial of the Gypsy (1978),
Chip and his Dog (1979),
A Bride from Pluto (1982),
The Boy who Grew too Fast (1982), and his final opera
The Singing Child (1993). His last opera for adults,
The Wedding Day, premiered in Seoul, South Korea, in conjunction with the
1988 Summer Olympics conducted by Daniel Lipton. In 1992, Menotti was appointed artistic director of the Teatro dell'Opera di Roma, a post he maintained for two years before being asked to resign over conflicts with the theatre's managers involving Menotti's insistence of staging Wagner's
Lohengrin. In honour of the 1995
Nobel Peace Prize, the
American Choral Directors Association commissioned
Gloria as part of the Mass celebrating the occasion. In 1996 Menotti directed his second filmed version of
Amahl and the Night Visitors. Menotti died on February 1, 2007, at the age of 95, at
Princess Grace Hospital in
Monaco, where he had a home. ==Musical style and critical assessment==
