As usual for the Christmas period, the BBC has a few Nonsense-related programmes you can listen to while still available on iPlayer Radio:
Drama of the Week, which you can download as a podcast, is Jeremy Iron’s reading of T.S. Eliot’s Old Possum’s Book of Practical Cats (this was first broadcast on 25 December in two parts).
Lewis Carroll’s The Hunting of the Snark was the Drama for Chrismas Day at 14:15, narrated by Tony Robinson with music by Katie Chatburn, Dorry Macaulay, Kathryn Williams, Stephen Cordiner and Jasper Wilkinson.
On the same day, Words and Music has “Sheila Hancock and Scott Handy read poems and prose on the festive theme of giving and receiving gifts. Through the words of writers from Robert Herrick to O. Henry, and from Edward Lear to Walt Whitman.” Actually, only one Lear limerick (There was an Old Man in a Pew, around 37:00) is read by Scott Handy with a nice music box accompaniment (Angel Polka).
If you want a decent amount of Lear, Naxos has just published Sir Derek Jacobi’s reading of The Finest Nonsense by Edward Lear (listing of poems from Naxos’s website): you can get it for free with an Audible trial.
