Watch Free Online on Hurawatch. The "lost" documentary of the Scottish music group The Blue Nile's tour of the US in 1990. In 1990, the film-maker Bernard Rudden made this documentary "Flags and Fences", which followed The Blue Nile on their tour of America. It's long been thought "lost", but writer, adventurer and all-round-gentleman, Trevor Ward, located and forwarded this copy, which captures Blue Nile as they seemed on the cusp of world success.
