Group to whistle 'Summer Nights'

The group will whistle the Grease hit 'Summer Nights' in today's task.

Charlie was called to the Diary Room and given instructions to read to the housemates.

They were asked to split into boys and girls and given a couple of hours to learn the song. Charlie is to act as conductor.

Throughout the performance, Big Brother's Booze-o-meter will be measuring the housemates' effort and enthusiasm. The more they put into their performance, the more alcohol they will receive after tonight’s eviction.

If Big Brother deems that the performance shows little effort or enthusiasm, the Booze-o-meter will go down and the housemates will receive little or no alcohol.
