In 1986, Du Prez contributed songs to the soundtrack of the Madonna and Sean Penn movie Shanghai Surprise: "The Hottest Gong in Town" and "Zig-Zag" (both sung by the film's executive producer George Harrison).
He is probably best remembered as playing the trumpet solo on the Modern Romance cover version of "Cherry Pink (and Apple Blossom White)" which made the UK top twenty in 1982.
Modern Romance scored seven further Top Forty hits before disbanding in 1985, including "Best Years of Our Lives" which reached number four on the UK Singles Chart and later featured in the movie Shrek.
They made a significant dent in the UK chart with the following singles: "Best Years of Our Lives", "High Life", "Don't Stop That Crazy Rhythm", "Walking in the Rain", and "Good Friday".
Du Prez left Modern Romance before they called it quits in 1985, but his trumpets sounds could be heard on their farewell single, "Best Mix of Our Lives" (1985), their last chart entry.
