Without wanting to be a devils advocate. If Neil Finn, Nick Seymour and Mark Hart decide to join forces with say Rob Hirst (ex Midnight Oil, excellent drummer / songwriter) on drums and do a series off concerts in Australia next year to celebrate the release of a you beaut ducks nuts Crowded House box set with bonus live material etc. and they play only "Crowded House" songs. Is it Crowded House?
Lets say that it all goes swimmingly well and the collective have a great vibe going on and they decide that they want to have a run through the US and Europe to support a CD with ten fresh tunes - is it Crowded House?
