Listen: Radio commentary reveals horror of Bradford fire

It's 30 years today since 56 people died, when a fire ripped through a football stadium as Lincoln City played Bradford City at their Valley Parade ground.

Today, a memorial service is being held to remember the victims of the 1985 disaster, with Lincoln's mayor and some councillors travelling to Yorkshire to represent the city.

Two Lincoln fans - Bill Stacey and Jim West - lost their lives. Tony Delahunty was commentating on the match 30 years ago - this extract reveals how the horror unfolded.
