Also Mollusca are slugs and snails (but not little boy parts).
Their inclusion in holiday humorous hymns is hit and miss.
Snaildartha is an experimental jazz album playing under the spoken word jazz of (The Story of Jerry the Christmas Snail). If that’s your thing, go with Thelonius. Or you could start with “A Snail is Born.” It’s different. Not exactly novelty Christmas music.
More outre are The Snails, post modern rockers from Baltimore with band mate names like Snailpril and Snailliam. Their “Snails Christmas (I Want a New Shell)” is just what you want to hear before you go clubbing.
Folk On is a comedy folk trio from Little Dribblepatch. Gloucester. Reminiscent of The Irish Rovers and The Kingston Trio, they know how to set a mood and tell a story. Listen to the saga of poor little “Ernie, the Christmas Slug” as he moves out of the regular rotation as ‘the Little Pet Slug’ and becomes the saviour of the working class.
