What happens on tour, stays on tour. Unless you're maverick Australian musician Nick Cave, then you scribble tour memories on a sick bag. And yes, that's sick bag as in the flimsy paper envelopes found in airline seat pockets.

During the Nick Cave & The Bad Seeds 22-city North American tour in 2014, Nick started jotting thoughts on to fully-functional sick bags (he's never actually been sick into one) and those notes later became a long form poem.

Bick's new book incorporates lyrical passages with straight prose and tells the story of a musician in his fifties touring the USA (it's fictionalised and 'not a tour diary' but parallel's Nick's own experience closesly). Bob Dylan, Bryan Ferry and Patti Smith feature (incidentally, this week Patti announced the release of a new memoir to follow Just Kids, M Train, which will be published in the autumn).
