A twitter opera about nuns, demons and birds will be performed in London this weekend after the Royal Opera House (ROH) composed a libretto from the popular microblogging site.
As part of an attempt to appeal to a wider audience, the ROH asked the public three weeks ago to "tweet" their contributions help create a story.
So far, around 900 people have used the twitter website to write 140-character tweets, and the volume of tweets has generated enough content for a seven-act opera, said ROH spokeswoman Sara Parsons.
"When pigs do fly, these birds will cry, and forever more leave torture to the devil. Bring me a pig!" was one of the contributions sent online.
