When the producers of ABC's 'Once Upon a Time in Wonderland' found themselves without the services of Who vocalist Roger Daltrey for an upcoming episode of the show, they turned to another rock legend who likes to leave his shirt unbuttoned: Iggy Pop.

Entertainment Weekly reports that the famous Stooge will be stepping in for Daltrey as the voice of the Caterpillar, the multi-legged hookah enthusiast who helped/tormented Alice in 'Alice in Wonderland.' 'Once Upon a Time in Wonderland' is the network's new spinoff of its hit series 'Once Upon a Time,' which uses fairytale mythology as the basis for a soapy saga of good versus evil; Daltrey had previously voiced the Caterpillar on an episode of the original series, but was reportedly unavailable for a return engagement.

Pop joins a cast heavy with name talent, including John Lithgow as the voice of the White Rabbit and legendary "that guy" Keith David as the voice of the Cheshire Cat. It's unknown how regularly he'll appear, but we can all start finding out on Oct. 10, when ABC airs the 'Once Upon a Time in Wonderland' series premiere.
