This weekend's Leeds Festival looks set to be a scorcher with a late return of summer - but Yorkshire's first music festival saw more than 200 people treated for exposure!

During the summer of 1970, West Yorkshire’s first serious attempt at a mini-Woodstock took place at Krumlin, above Halifax. However, the event was an utter shambles and a near disaster.

With a whole host of stars lined up, Georgie Fame, Alan Price and Manfred Mann, it was Elton John, who managed to charm the 15,000 crowd before the weather turned vicious.

Although it was August, temperatures dropped to low 40s - about 5 degrees celcius - and gales howled down the valley.

When the storm broke at midnight, the fire-lit scene became what organisers described as a “living hell.” Conditions were impossible and the plug had to be pulled on all acts until it became safe to play again without fear of electrocution.

A special air-inflated folk tent had deflated like a punctured tyre and the Press tent had lurched on its side. At the top of the site, a huge dry-stone wall had also been blown over by the strong winds.

At least 200 people were treated for exposure and serious loss of temperature and shivering fits. Three nearly suffocated as they tried to protect themselves from the night-time weather in giant polythene bags and complaints were about the price and quality of the food (10p for a hamburger was a lot of money in those pre-decimal days).
