John Cage goes on and on and on

He never stops making us smile, and laugh.

The first notes in the longest and slowest piece of music in history, designed to go on for 639 years, are being played on a German church organ on Wednesday.

The three notes, which will last for a year-and-a-half, are just the start of the piece, called As Slow As Possible.

Composed by late avant-garde composer John Cage, the performance has already been going for 17 months - although all that has been heard so far is the sound of the organ's bellows being inflated.
