British jazz-rock band Mogul Thrash evolved from James Litherland's Brotherhood, which in addition to guitarist Litherland (an alumnus of Colosseum who was a founding member of the group in 1969) also featured guitarist/reedist Michael Rosen (previously of Eclection, not the children's poet/author), drummer Bill Harrison and the so-called "Dundee Horns"—saxophonists Roger Ball and Malcolm Duncan.
With the addition of singer/bassist John Wetton, formerly of short-lived London band Splinter (not to be confused with the vocal duo from South Shields), the group rechristened itself Mogul Thrash: There was a TV programme that everybody used to watch on a Saturday night called the Michael Miles Show and he had on it a game called the “Yes No Interlude” where he would ask contestants questions very quickly, and they would have to answer without using either Yes or No.
The late great Spike Milligan had his own show and it was hilarious and the band would watch it every week without fail, sometimes we would be in tears of laughter.

However, faced with legal problems with their management, Mogul Thrash was forced to disband shortly after the record's release; while Wetton went on to join Family and later King Crimson, UK, and Asia, Duncan and Ball soon reunited in Average White Band.
