Steve Bell - a self-confessed rocker and veteran of both Download and its predecessor Monsters Of Rock - is a director of care with the Motor Neurone Disease Association and was the first person in the UK to film his own ice bucket challenge.

And he couldn't have been more proud of the rock community when he saw the likes of Dave Grohl, Duff McKagan, Def Leppard, Kiss and Jason Becker taking part. Guitar virtuoso Becker has ALS and performed a modified version of the challenge as he thanked everyone who had taken part.

The 2014 social media phenomenon saw people from all walks of life taking part in a stunt that saw them pour buckets of ice cold water over their heads to raise awareness of motor neurone disease (MND) - also known as amyotrophic lateral sclerosis (ALS) and Lou Gehrig's disease.
