When Horn offered Bob Geldof and Midge Ure the studio free of charge for 24 hours to record the charity single, but was unavailable to produce it, Bruce was approached to engineer and mix what became one of the biggest selling singles ever.
With many of the most famous artists of the time participating, and seven film crews in attendance, he worked straight through that day and night.

[4] Bruce has worked with many leading artists from the 1980s onwards, including Duran Duran, Spandau Ballet, Kate Bush, Stevie Wonder, Bob Marley, Art Garfunkel, Yes, Van Morrison and Nik Kershaw.
He played slide guitar on Frankie Goes to Hollywood's "The Ballad of 32" and his spoken voice can be heard on their cover of "Born to Run".
