Really? I'll take your word for it although I'd appreciate a second opinion from Claud9's roomie.
Anyway, a different metaphor is in order. How 'bout....... Brian Wilson and Joni writing a song together wouldn't work because........ 'Altoids (TM) breath mints and Ricola (TM) breath mints don't mix.' Better? As Rosie O'Donnell said, "Oh, that's awful." Lama "RSM" said, >>>> Not to quibble with your critique of a Mitchell/Wilson collaboration, but a good Mexican chicken mole will blend chocolate and garlic in a heavenly fashion.
