The Police stars Sting and Stewart Copeland often fight during rehearsals for their comeback tour - but always make-up before they go on stage.
The band split in 1986 and have reunited for a one-off tour, but drummer Copeland says the rehearsals are often spoilt by a series of arguments.
He says, "There were fights and there still are. Verbal, they were never physical. These days we're on a three or four-day cycle.
"We're playing nicely, then the little rubs and grinds start, you know, 'Stewart, don't play that', Sting, I wanna. Then, Nyanyanyanyannnnnn... 'You f**king...!' Stomp off. Errrrrrgh! It drives me nuts and I'm thinking, I don't need this, I'm not going to put up with this.
"Then, a little later it's Sting? 'Stewart?' You know I love you. 'You know I love you too'. Two grown men kissing and hugging tearfully. After that we're on our best behaviour. Until he starts. And I start."
