Difford &amp; Tilbrook (album): 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.

Some Fantastic Place: 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.
