The Hoosiers' world record attempt
The Hoosiers are "smugly confident" they will break the world record for the longest song.
The British-Swedish pop rockers - frontman Irwin Sparkes, guitarist Martin Skarendahl and drummer Alfonso Sharland - are aiming to break the record for the longest ever song to be released as a single in the country.
They will record the single, Stop Giving Me Verses, on July 26, with contributions from fans.
"We are smugly confident - we are aiming for 43 minutes (a nice round number) as the current record is a weedy 41!" said Alfonso.
The trio, whose new single Choices will be released on August 1, and album The Illusion Of Safety on August 16, have asked fans to send them new verses for the charity track.
In return, a picture of the writer will appear on a screen in the video as the song is being recorded. They will also get their snapshot shown on the sleeve of the download release, and a credit.
All proceeds from the track will go to Teenage Cancer Trust.
