The legendary actor played an eccentric director in the 2014 music video, set in a desert, where he gave each of the boys a persona: love, light, power, danger and mystery.

Speaking on The Jonathan Ross Show, actor Danny said: ""They asked me to join the band but I figure, well listen all these 19 years olds and a 70 year old crazy man, no you don't want to do that! It was a lot of fun. I had a great time, the boys are very, very spirited and fun!"
Danny also spoke about the late Robin Williams, who was a close friend and colleague of his.
"I remember when he started Mork & Mindy, our show was on stage 25 he was on 27 so we'd all go down, we'd heard about this amazing guy and he was amazing. An amazing, amazing talent. [It's] very sad that he's gone but he was dangerous because Robin was very funny and I remember the first time I had this experience with him, I just cracked up totally.
"We went swimming, there was a swimming pool at somebody's house and I was sweltering hot, I just dove in the pool and I don't swim very well and he started telling jokes and he almost killed me in the deep end!"
The Jonathan Ross Show airs Saturday, 7 November at 10.10pm on ITV.
