The Lord of the Rings - The Musical

TLOTR- The Musical; WHY?? One of my insane boyhood chums once sent me "The Lord Of The Rings- The Heavy Metal Album" (with such stirring anthems as Gollum's "Gimme Da Ring" or summink) and I thought that was bile. But this is DIRE! I was only today regaling Mah Wahf with the theorem that the musical is dying because it cannot support an original Idea. The last few successful "musicals" have all seemed to be derived from other source material. The Producers? Wicked? Dirty Rotten Scoundrels? Jerry Springer- The Opera? We Will Rock Somebody With No Ears? Mamma Mia? Even the bilious RENT is a rip-off, or should I euphamise, "update"? What's next? "Schindler's List- The Ice Spectacular?" Is there (and I ask this out of purely masochistic interest) any SUCCESSFUL musical in the last ten years NOT adapted/derived/stolen/revised from another source? You're mah wahf now!
