Aussie rocker Nick Cave says he struggles to find young singers to fulfil choral duties at his live shows because their parents often ban the youngsters from singing his lyrics.
The veteran star is known for tackling dark subject matters in his songs, including gun massacres, serial killers, infanticide and mass murder.
Push the Sky Away, the 15th studio album from Nick Cave and the Bad Seeds, features a children's choir - but recreating the sound onstage is proving tough because Cave's tactic of recruiting a local choir from each stop on his tour is causing problems.
"Sometimes you have to have three or four goes at finding the choir," he told The New Review magazine.
"They come back going, 'No, no, no.' Especially in (the US).
"There were certain songs they wouldn't sing. They won't do Mermaids, for instance, because of the lyrics.
"Personally I find that ridiculous, but maybe I'm more liberal with things.
"Anyway, often people feel it's inappropriate, and they don't want their children around words like 'snatch'."
Earlier this year, on the opening date of the band's Australian tour, Cave bellowed in jest to members of the front row who attempted a half-hearted stage rush at the Sydney Opera House: "This is the Opera House but you can't touch my c*ck", momentarily forgetting the choir of young school girls gathered in the shadows waiting to perform.
"Oh I'm sorry, so sorry," he gingerly corrected, later making sure the girls were "OK" on several occasions to universal acknowledgments of the affirmative.
