Gardens, balloons, parties and whales feature in this week's cabaret of the word. Ian's guests include Toby Litt, Roger Robinson, Hannah Silva and Caleb Femi. Novelist, poet and librettist Toby Litt has wrestled Ian, written stories backwards, and been limited to a single verb, in previous Verb commissions. This week he has to write something surreal for us, and then write something even more surreal by the end of the show - whilst blowing up two balloons. Toby is also mine of writing advice and genre-challenging playfulness in his novels, in his book 'A Writer's Diary' and in his substack. Roger Robinson's 'A Portable Paradise' won the T.S.Eliot Prize and there's no one better placed to unpick a poem and explain its most extraordinary lines for The Verb. He shows us how language really works on this week's show, as he does in his books 'On Poetry' and 'On Creativity'. Caleb Femi is an award-winning poet and film-maker. He has said he wants to be a merchant of joy, and there's lots of joy in his celebration of the true meaning of parties in his new collection 'The Wickedest'. Caleb shares new poems with Ian. Hannah Silva is a poet who truly understands how sound can let us into meaning. She performs a brand new commission for The Verb on the balloon - and asks Ian and his guests to play keepy-uppy during the show. Her latest book is 'My Child, the Algorithm' .
