During October 1971, Spectrum formed a side project, [b][/b], using the same line-up of on vocals and guitar, on electric piano, on bass guitar and on drums. They performed at pubs, and local dances, playing a more dance/pop-oriented repertoire and using a simpler set-up than when performing as Spectrum. By September 1972 Neale had left both bands; he was replaced by on keyboards.

In April 1973, Spectrum disbanded which also ended Indelible Murtceps. Mike Rudd, Bill Putt and John Mills co-founded in mid-1973 a new group, [a=Ariel (13)].

In 1999 Spectrum reformed as [b]Spectrum Plays the Blues[/b] around the nucleus of Mike Rudd, Bill Putt, John Mills with the addition of some new members. They issued two albums, [i]Spill[/i] (March 1999) and [i]No Thinking[/i] (June 2004) before they trimmed the name back to Spectrum. Bill Putt passed away on 7 August 2013.
