In addition, he was commissioned by Disney to compose the score for their fireworks show IllumiNations: Reflections of Earth and a parade called Tapestry of Nations at Epcot. The resulting pieces of music from the fireworks show have been used by Disney since 1999. With the permission from Disney, who hold the full rights to the composition and the Hal Leonard corp. who hold the publishing rights, Reflections of Earth has now been arranged for the idiom full symphonic wind band and dedicated to the Pennsylvania Symphonic Winds and their musical director Phil Evans. The first performance of this arrangement was in Radnor PA on December 2nd 2012. For Tokyo DisneySea, he composed the score for "BraviSEAmo!", the pyrotechnics and water nightly show in 2004.

His music was heard during the 2010 Winter Olympics opening ceremony.

Greenaway was one of the composers commissioned to write music for the Thames Diamond Jubilee Pageant in 2012 in honour of the Diamond Jubilee of Elizabeth II. The piece, entitled The New Water Music, was inspired by the George Frederic Handel's Water Music and contained movements by several modern British composers working under the direction of Greenaway. After the pageant, Greenaway was critical of the BBC coverage of the pageant as the live broadcast did not feature the performance at all. In his personal blog, he expressed the view that the presenters had focused on interviewing celebrities and while ignoring the musicians completely. Read more on Last.fm.
