Who played the composer Franz Liszt in the 1975 film 'Lisztomania'?

Lisztomania is a 1975 film by Ken Russell, drawn from a biography of Franz Liszt.

Depicting the flamboyant Liszt as the first classical pop star, Lisztomania features contemporary rock star Roger Daltrey (of The Who) as Franz Liszt. The film was released the same year as Tommy, which also starred Daltrey and was directed by Russell. The film is derived, in part, from an actual "kiss-and-tell" book, Nélida, by Marie d'Agoult. The novel is a "thinly disguised fictional account" of her four-year affair with composer Franz Liszt.

The term "Lisztomania" was coined by the German romantic literary figure Heinrich Heine to describe the massive public response to Liszt's virtuosic piano performances. At these performances, there were allegedly screaming women, and the audience was sometimes limited to standing room only.

Rick Wakeman, from the progressive rock band Yes, composed the Lisztomania soundtrack, which included synthesiser arrangements of works by Liszt and Wagner. He also appears in the film as the Nordic god of thunder, Thor. Daltrey and Russell wrote the lyrics for the soundtrack, and Daltrey provided vocals.

Of the other rock celebrities appearing in the film, Ringo Starr, drummer of The Beatles, appears as the Pope.
