Emerging from the cult 1980s band The Pale Fountains, Shack experienced various lineup changes and challenges, including the loss of early recordings in a studio fire.
In the 2000s, Shack signed with Noel Gallagher's Sour Mash label and released albums like ...The Corner of Miles and Gil (2006).
Bassist and founding member Chris "Biffa" McCaffrey died of a brain tumour in 1989, a few years after the band broke up.
At the time, Allison was in Los Angeles, and when he returned, it transpired that he had left the copy in his hire car.
Shack split, with Wilkinson joining fellow Liverpudlian John Power (formerly of The La's) to form the successful Britpop band Cast.
The Head brothers, along with Iain Templeton (who drummed on The Magical World of The Strands) and bassist Ren Parry re-formed Shack in 1998, releasing H.M.S.
In October 2007, the band released their greatest hits compilation album, Time Machine, including two new tracks.
In February 2008, the band re-formed the Pale Fountains for two critically acclaimed live shows in Liverpool and London.
