John Shuttleworth is one of those comic performances which, for me, works as a complete thing, but doesn't split into soundbite jokes.
I've heard his radio spots over the years and enjoyed them but I wouldn't listen to his songs as a standalone piece of humour. For instance, with "Savoury", I fully understand the dilemma, I've been there myself, but the song is longer than the joke and for me would have worked better with fewer verses.
I have no problem with a performance as a "character". I grew up listening to the Clitheroe Kid on the home service, thought Lily Savage was hilarious. Let's face it, who ever really knew what Tony Hancock really was. All we saw or heard was the character which looked and sounded like the man. John Shuttleworth can be poignant and the writing can be very clever, but never cruel, unlike what a lot of people sell as comedy.
Quack!
