Iron Maiden have paid tribute to late comedian Robin Williams, recording a song in his homour.
The metal rockers are to release their latest album 'The Book Of Souls' in September, their first record since 2010's 'The Final Frontier'.
Speaking in Italy frontman Bruce Dickinson explained how his favourite track from the forthcoming album was written by guitarist Adrian Smith and bassist Steve Harris about Williams.
"My favourite song is one I didn't write," Dickinson explained. "It's 'Tears of a Clown', which talks about Robin Williams. I ask myself how could he be so depressed when he always seemed to be so happy."
Robin Williams committed suicide in August 2014 after struggles with depression and addiction.
