Acme 472 Slide Whistle

Many will recognize the slide whistle as the voice of the Clangers, but just listen to Louis Armstrong playing Who’s It to see its musical possibilities. With many claims to fame it features prominently in ‘Swanee- Kazoo’ in Radio 4’s I’m Sorry I Haven’t a Clue, and on The Simpsons as Sideshow Bob’s voice before he found his own.
