Frank John Musker, born in 1951, is a British songwriter and composer renowned for his prolific work during the 1980s and 1990s. He collaborated with a diverse range of artists, including Sheena Easton, the Babys, Robert Miles, Jennifer Rush, Bucks Fizz, Air Supply, Lucio Battisti, Zucchero, Lisa Stansfield, and notably, Brian May of Queen. Musker's collaboration with May on the song "Too Much Love Will Kill You" earned them the Ivor Novello Award for Best Song Musically and Lyrically in 1997.

Musker's early success came with the 1977 North American hit "Heaven on the 7th Floor," co-written with Dominic Bugatti. The song became a hit for Paul Nicholas and The Mighty Pope. Musker and Bugatti also worked with John Waite of the Babys to write "Back on My Feet Again," which became the Babys' last top 40 hit in 1980. In 1982, Musker and Bugatti released an album under the name The Dukes, produced by Arif Mardin.

As a solo artist, Musker recorded the song "Steely Man" in 1984, which was featured in the film Grandview, U.S.A. By 1998, he was serving as a director at the British Academy of Songwriters, Composers and Authors. Despite his significant contributions to music, Musker has maintained a level of anonymity, valuing the creative freedom that comes with being a songwriter.
