Ex-world champ Zac 'The Magnet' Munro has some tips for this year's UK Air Guitar Championship contestants.

The event takes place on Friday at the Carling Academy in Islington, north London.

The UK Air Guitar website claims: "The Purpose of the Air Guitar World Championships is to promote world peace.

"According to the ideology of the Air Guitar, wars would end and all the bad things would disappear, if all the people in the world played the Air Guitar.

"You can steal our mobile phones, our cars and the shoes on our feet, but you cannot steal something that is invisible."
