On 31 December 1999, a piece of music started playing in a lighthouse on the River Thames in east London.

It’s called Longplayer, and it’s set to keep going, without repeating, until the year 2999.

It was created by Jem Finer from The Pogues, using 234 Tibetan singing bowls.

Megan Jones meets Jem to find out why he wanted to create a one thousand year long musical composition.
