Wayne Coyne of Flaming Lips in concert, The Roundhouse, London

Music review: The Flaming Lips, The Roundhouse, London

"I feel a whole lot better," maintains a hoarse Wayne Coyne, apologising for being too ill to play the previous day's cancelled concert before informing us that "being sick is pretty petty" compared to the tornado disaster in Oklahoma, his home state.

It began with a banana. In an effort to entertain his two children at breakfast one day, the graphic-designer-cum-photographer Brock Davis put the brain that has carried him through 17 years of creative thinking in the advertising industry into gear, and fashioned a section of the peel into a hat for the banana to wear.

Dolphins: ‘the rapists of the sea’

Telegraph blogger Tim Stanley, a conservative historian of the US, has taken issue with the American Catholic college Fordham University over their decision to include bioethics professor Peter Singer in a panel discussion.
