Boy George thinks prison was similar to school.

The Culture Club singer - who spent four months in prison in early 2009 for assault and the false imprisonment of a male escort - believes spending time in HMP Pentonville and HMP Edmunds Hill was not as tough as many would believe.

He said: "You just get on with it. You make friends. You go for coffee. You swap CDs. It's like being in school. Except you can't leave."

The 49-year-old star also received a rendition of his 1983 hit 'Karma Chameleon' when he entered prison for the first time, but insists it doesn't upset him as it is a reaction he often receives when he meets people.

He said: "I get that everywhere. At carpet markets in Morocco, by the pyramids in Egypt.

"I was expecting it, much like the environment, which is like the classic Victorian prisons you see in the movies; safety nets, balconies and everything pained drab green and yellow."

The singer - real name George O'Dowd - spent most of his time in incarceration reading books, and impressed fellow inmates with his cooking skills.

He said: "I spent a lot of time reading; everything from 'Wuthering Heights' to 'Catch-22' to 'A Confederacy of Dunces' and listening to David Bowie records.

"I also took a job in the kitchens. I don't want to blow my own trumpet, but the first time I made a quiche this black guy went, 'Tasty. Batty man made the quiche.' "
