You young folks may not remember, but the Copeland brothers were enormously influential in independent music back in the day, particularly in the U.S.: Miles as the president of I.R.S. Records and Ian as booking agent for numerous bands such as R.E.M., the Cramps, Police, the B-52's and pretty much every interesting band from Britannia. Just sayin'. Their television show "the Cutting Edge" was where I first saw X, Henry Rollins (with long hair, reciting his poetry!), Wall of Voodoo, Fleshtones, Let's Active, etc.
Stewart is a very exuberant guy and it's easy to sort of want to distance yerself when he's in full spaz mode. But he does make a good point. Considering how genius and influential the Talking Heads were, isn't it sad that they can't put their egos aside (ahem, Mr. Byrne) and get together, while they are still relatively spry and able to perform.
The Smiths obviously have a more complex situation (what with the legal situation) but I hope Morrissey 'n Marr can see their way to working together again someday, if they would like.
