Sky was a London-based progressive rock band, formed in 1978 when classical guitarist John Williams decided to team up with Herbie Flowers, Francis Monkman, Tristan Fry and Kevin Peek. After a protracted search for a record company, they eventually signed with the small European label Ariola Records. Their self-titled debut album was highly successful in Britain and Australia. Their follow up double album, "Sky 2", was even more so being the tenth highest selling in Britain for all of 1980.
In 1980, British producer Martin Lewis conceived of presenting Sky in a concert performance at London's Westminster Abbey - the 900-year old historic church in the center of London. The concert eventually took place in February 1981. It was the first-ever rock concert held at the Abbey and it was video-taped for a BBC TV special - subsequently released on home video. The concert was a benefit for the human rights organization Amnesty International and commemorated the organization's 20th anniversary. The landmark event resulted in Sky receiving considerable positive media coverage.
