Context: Smithereens is a 1998 album from UK singer-songwriter Nick Harper.

Difford & Tilbrook are the songwriting team of Chris Difford and Glenn Tilbrook, known for their work as the principal writers for the new wave rock band Squeeze.  In addition to playing guitar for the band, they are responsible for the group's many hits, including "Cool for Cats", "Up the Junction", "Another Nail in My Heart", "Pulling Mussels (From the Shell)", "Tempted", and "Annie Get Your Gun".  They have both written independently outside the band, and together wrote the music for the British sit-com "Girls on Top" starring Dawn French, Jennifer Saunders, Ruby Wax and Tracey Ullman. Kyo (京 , Kyō ) is a Japanese musician, poet and singer-songwriter.  He is best known as the vocalist of the metal band Dir en grey.  He has been with the band since its inception in 1997 and was formerly in La:Sadie's.  Kyo was inspired to become a musician when he saw a picture of Buck-Tick vocalist Atsushi Sakurai on the desk of a junior high school classmate.  His vocals span a tenor range. Difford & Tilbrook is the only studio album released by Difford & Tilbrook.  Chris Difford and Glenn Tilbrook were the main songwriters in the new wave band Squeeze until their 1982 breakup.  The duo continued to write songs together, and in 1984 released this self-titled effort.  The album received a very limited pressing as a CD in Japan only, and these have become valuable collector's items. The Incomplete Glenn Tilbrook (2001) was the first solo release by lead singer of Squeeze Glenn Tilbrook.  This album featured Tilbrook's first recordings of songs written without his fellow Squeeze member Chris Difford.  (While Squeeze never recorded a solo Tilbrook composition, The Rumour did so in 1981.) The Fluffers is the name of Glenn Tilbrook's band when Tilbrook performs without Squeeze.  They tour internationally, and consist of Tilbrook, Stephen Large (keyboards), Simon Hanson (drums) and Lucy Shaw (electric bass). Glenn Martin Tilbrook (born 31 August 1957) is the lead singer and guitarist of the English band Squeeze, a band formed in the mid-1970s who broke through in the new wave era at the decade's end.  He generally wrote the melody for Squeeze's songs, while his writing partner, Chris Difford, wrote the lyrics.  In addition to his songwriting skills, Tilbrook is respected both as a singer and an accomplished guitarist.  He was born in Woolwich, London. Some Fantastic Place is a 1993 album by the British new wave group Squeeze.  It was the band's tenth studio album, and it marked the departure of drummer Gilson Lavis, the only band member besides Chris Difford and Glenn Tilbrook who had appeared on every Squeeze album to this point (Lavis was replaced by Pete Thomas).  This record also marked the brief return of keyboardist/vocalist Paul Carrack.  Carrack had last appeared on 1981's "East Side Story", performing the lead vocals on one of Squeeze's most popular early singles, "Tempted."  "Loving You Tonight" became only the second Squeeze song cut in thirteen years to feature Carrack singing a lead part.  Additionally, bassist Keith Wilkinson wrote and sang "True Colours (The Storm)", the first song on a Squeeze album not written by Glenn Tilbrook, Chris Difford, Jools Holland, or any combination of those three.  The record was produced by Squeeze and Peter Smith.
