After the Fire was a British prog rock/new wave band that originally formed in 1971 in London, England. They are one of a small group of acts to be a one hit wonder in both the UK and US with entirely different songs (1979's "One Rule for You" and 1982's "Der Kommissar", respectively).
These are videos from concerts where After the Fire played, so they may be of other bands that played the concert as well.
