Bob K.: >What is the famous collaborative piece by Les Six? Is it "Les Maries de >Tower Eiffel?" Is anyone familliar with this piece? I believe each of them >wrote 1 movement? Is this useful to this collaboration discussion? Can one >have a paragraph made entirely of questions? I've reviewed this work at the ClassicalNet web site. All is as Bob says, except that Durey did not contribute. So it was 5/6 of Les Six. Two other famous collaborative works include "L'eventail de Jeanne" by various 20th-century French composers, including members of Les Six, Ravel, and, I believe, Florent Schmitt and Jacques Ibert, though I'm not sure of the last two, and the original version of Der Lindberghflug by Weill and Hindemith. I should also mention the 24 Paraphrases on "Tati-tati" (the Russian version of "Chopsticks") by Liszt and members of the Mighty Five (minus Mussorgsky) and Variations on "Tati-tati" by members of the Russian Five. Whether any of these are truely full collaborations is open to dispute. Only one composer worked on each (rather distinct) section. Steve Schwartz
