We're celebrating Halloween tonight on The Tom Dunne show by taking a look at the creepiest instrument of them all - the theremin.

Not sure what a theremin is?

It's an electronic musical instrument that produces a unique sound that's been used in many horror film scores.

It's played by moving the hands in the air - through the antennas’ invisible electromagnetic fields.

It's a wonderful thing to watch.  We'll be joined by one of the very few theremin players in Ireland, Dr Garvan Browne who'll give us a live performance.

Also John Moynes continues his look at comedy sitcoms with a chat about British sitcom Only Fools and Horses.

On Newstalk tonight from 10pm.
