They performed only a handful of live concerts, spending most of their time in the studio.  In early 1988, they played their last gig at the Infamous Assylum Club, Manchester and then disbanded.  Their only recording that survived from the Nyrex studio sessions in Manchester was the non released single Scam Man/Electric Hands which to this date has never been officially released into the public domain.  in 1989 Jules and Steve linked up with Leeds band The Kennedy Pill.  After a nationwide tour they released their only single, Beside the Sea, before disappearing into obscurity.  Jules then went on to complete his degree, whilst Steve continued to concentrate and develop his career as an industry respected sound engineer and formed the band Klammer.  Bill moved to Manchester and then later, left the UK to live overseas in Russia and the Middle East.  Meanwhile, Graham went and pursued a teaching career.  The band's influences were extremely varied however there was some leaning towards the Leeds Gothic rock scene at the time, with such bands as The Sisters of Mercy, The March Violets and The Mission providing a source of inspiration for the lyrics and style especially in the early days of the band.  The Flying Hendersons are contemplating a comeback gig in 2017 to mark their 30th anniversary. "Ignorance" is a song by American rock band Paramore.

U2 invited The Walls to support them at their second show in Slane Castle in 2002 after the band sent them copies of their debut.  A number of songs from "Hi-Lo" featured in movies: Goldfish Memory, On the Edge, and Dead Bodies.  In 2002 they released the single "To the Bright and Shining Sun".

The 2013 movie Begin Again starring Keira Knightley and Mark Ruffalo features "Drowning Pool" over the opening credits.

They played SXSW in Austin, Texas, a few days beforehand.  The following year the band travelled to Australia and played their first shows there, opening up for Crowded House on the latter's first reunion gigs.

The Hunger is an industrial rock band from Houston, Texas formed by brothers Jeff and Thomas Wilson along with Brian Albritton.  During the initial year of putting the band together and working on new material the band wrote and independently released the single, "Shock" in 1991 which rose to the top of the dance charts.  Industrial dance music ruled the charts in Europe along with strong ties to Chicago, Wax Trax Records, and Houston.  Subsequent releases of "Cut the Skin" and "Shoot to Kill" gained national exposure on the dance charts and club scene.  "Never Again" was self-released as a radio single and quickly rose to the top of Houston Radio Station's 93Q and 96.5 attracting the attention of independent record label Alpha International.  Stephen Bogle produced the single of "Never Again".  The band wrote and produced the album "Leave Me Alone" but due to the bankruptcy of Alpha International the record sat idle.  It was released but there were no marketing efforts behind it.  After the release of the album, the band sought out drummer Max Schuldberg and they played their first concert as a foursome opening for Peter Murphy at Southern Star Amphitheater.  They played concerts in Texas as a foursome for two years.  Along with the three founders and newest member Max Schuldberg, the band added producer Stephen Bogle as guitarist to complete the line up.  The band recorded and produced "Grip" under their own start up label, Gut Records.  "Grip" went on to sell 15,000 units with the help of a crafty rework of Bad Company's "Feel like Makin Love".  Universal Records, at the time a brand new start up label, heard of the success of "Grip" and signed the band as their second artist ever.  "Devil Thumbs a Ride", the 3rd album, had already been recorded and mastered and was about to be manufactured for another self-release when Universal stepped in to sign the band and release the album as-is.  The Hunger had a hit song in 1996, "Vanishing Cream", from the "Devil Thumbs a Ride" CD, which received heavy airplay on rock stations and reached No. 4 on the Mainstream Rock charts.  After two years of constant touring, the band finally stopped to record their second release with Universal Records, "Cinematic Superthug".  After only moderate success with the single, "Moderation", the band asked to be and was granted a release from their contract from Universal Records.  Two songs, "Shoot to Kill", also from "Devil Thumbs a Ride", and "If", from "Grip", reached No. 42 on Billboard's Dance/Club Play chart.  The band has released six albums: two on Universal Records and four on independent labels. Former original drummer (1991-2003) Max Schuldberg (voted 2002's Best Drummer by the Houston Press Music Awards) parted with the band after the five albums in 2003 and moved to Los Angeles.  Former guitarist and two time Grammy Award nominee (remixer, for his work with D.J. Cubanito) Stephen Bogle now Produces artists in the Metal, Electronic, and Pop genres.  In late 2005 Stephen Bogle parted ways with the band, and Tim Huston was quickly picked up.  With having only a few practices with the band they headed on tour with Ten Years.  Tim Huston Stayed with the band from late '05 til 2013.  "The lifestyle was just getting to overwhelming for me to handle".  "If I would have stayed, who knows what would have happened to me.  There was just no off button".  In 2013, guitarist Raf Rivera joined the lineup, and the band is currently in the process of recording their first new material in over 8 years.
