Ananova:

Liam and Noel Gallagher have reportedly insisted on a drugs free zone when they play Glastonbury this week.

The Oasis frontmen told organisers they do not want any trace of illegal substances backstage.

The Gallaghers were notorious for their bad boy image but say that's all behind them now.

"They have done the whole bad-boy rock thing and now they are respectable adults with children," a source close to festival organisers told the Daily Star.
