Answer the question at the end by quoting:

Yusuf Islam (born Steven Demetre Georgiou; 21 July 1948), commonly known by his former stage name Cat Stevens, is a British singer-songwriter and multi-instrumentalist. His 1967 debut album reached the top 10 in the UK, and the album's title song "Matthew and Son" charted at number 2 on the UK Singles Chart. Stevens' albums Tea for the Tillerman (1970) and Teaser and the Firecat (1971) were both certified triple platinum in the US by the RIAA. His musical style consists of folk, pop, rock, and Islamic music.
On 15 September 2014, Yusuf announced the forthcoming release on 27 October 2014 of his new studio album, Tell 'Em I'm Gone, and two short tours: a November 2014 (9-date) Europe tour and a December 2014 (6-date) North America tour, the latter being his first one since 1976. On 4 December 2014, he played to his first public US audience since the 1970s at the Tower Theater in Philadelphia.  Yusuf performed two shows in early 2015: on 27 February at the Vina del Mar Festival, Quinta Vergara, Vina del Mar, Chile and on 22 April at the Wales Millennium Centre in Cardiff Bay, area of Cardiff, Wales, UK.  On 1 June 2016, Yusuf shared a new song called "He Was Alone" and its corresponding video. Part of his newly launched fundraising campaign for child refugees, #YouAreNotAlone, the song was inspired by a trip to southern Turkey's camps for Syrian refugees. He performed the song live for the first time in a special charity concert, his first show in more than a year, on 14 June 2016 at the Westminster Central Hall in London.  On 26 July 2016, Yusuf announced he would be part of the Global Citizen Festival held on 24 September 2016 in Central Park, New York, New York.  On 9 August 2016, Yusuf announced "A Cat's Attic Tour", his second North American tour since 1978, beginning on 12 September 2016 at the Sony Centre for the Performing Arts in Toronto and ending on 7 October 2016 at the Pantages Theatre in Los Angeles. The string of 12 dates roughly coincides with the 50th anniversary of his first single, I Love My Dog, and would "feature a limited run of stripped down, introspective performances." The tour included three shows in New York City (two shows at the Beacon Theatre and one show in Central Park at the Global Citizen Festival), his first shows in New York City since 1976. In keeping with his spirit of humanitarianism, he would be donating a portion of the revenue from each ticket sale towards his charity Small Kindness, as well as UNICEF and the International Rescue Committee in an effort to assist children affected by the current Syrian refugee crisis.

Did he do any other fundraising or charitable work?

He performed the song live for the first time in a special charity concert, his first show in more than a year,

IN: La Strada (lit. "The Road") is a 1954 Italian drama film directed by Federico Fellini from his own screenplay co-written with Tullio Pinelli and Ennio Flaiano. The film portrays a naive young woman (Giulietta Masina) bought from her mother by a brutish strongman (Anthony Quinn) who takes her with him on the road. Fellini has called La Strada "a complete catalogue of my entire mythological world, a dangerous representation of my identity that was undertaken with no precedent whatsoever."

In later years, Fellini explained that from "a sentimental point of view," he was "most attached" to La Strada: "Above all, because I feel that it is my most representative film, the one that is the most autobiographical; for both personal and sentimental reasons, because it is the film that I had the greatest trouble in realizing and that gave me the most difficulty when it came time to find a producer." Of all the imaginary beings he had brought to the screen, Fellini felt closest to the three principals of La Strada, "especially Zampano." Anthony Quinn found working for Fellini invaluable: "He drove me mercilessly, making me do scene after scene over and over again until he got what he wanted. I learned more about film acting in three months with Fellini than I'd learned in all the movies I'd made before then." Long afterwards, in 1990, Quinn sent a note to the director and his co-star: "The two of you are the highest point in my life -- Antonio."  Critic Roger Ebert, in his book The Great Movies, has described the current critical consensus as holding that La Strada was the high point of Fellini's career and that, after this film, "his work ran wild through the jungles of Freudian, Christian, sexual and autobiographical excess". (Ebert, himself, disagrees, seeing La Strada as "part of a process of discovery that led to the masterpieces La Dolce Vita (1960), 8 1/2 (1963) and Amarcord (1974)".)  The years since its initial release have solidified the high estimation of La Strada. It holds a 97% rating on the review aggregator website Rotten Tomatoes from 31 reviewers who, on average, scored it 8.7 on a scale of 10. Its numerous appearances on lists of best films include the 1992 Directors' poll of the British Film Institute (4th best), the New York Times "Best 1,000 Movies Ever Made", and the "Greatest Films" list of They Shoot Pictures, Don't They (# 67) - a website that statistically calculates the most well-received movies.  In 1995, the Catholic Church's Pontifical Commission for Social Communications issued a list of 45 films representing a "...cross section of outstanding films, chosen by a committee of twelve international movie scholars." This has come to be known as the Vatican film list, and includes La Strada as one of 15 films in the sub-category labeled Art. Pope Francis, has said it is "the movie that perhaps I loved the most," because of his personal identification with its implicit reference to his namesake, Francis of Assisi.

Who else was cast other than Quinn ?
