'America's 250th birthday is our 50th anniversary'

For Roger Lieb and Bonnie Taff, this 4 July is a double celebration. Their 50th wedding anniversary falls on America’s 250th birthday.

The California couple, both 82, wed on 4 July 1976 – America's bicentennial. With huge fireworks and parties across the US, they say it felt like the whole country was celebrating with them.

Fifty years later the pair, and their best friend who was at the wedding, tell the BBC how it felt to mark the two milestones at what was "a very celebratory time" for the nation.
