Flash Mobs...?

The fantastic new T-Mobile advert filmed in Heathrow Airport "Welcome Back" has got me thinking about flash mobs. The amount of effort that goes into the production of these cannot only be done by a creative agency surely? How the songs mix and congeal must have used Choreography and brought skills from other sectors to the industry. This has made me ask the question are choreographers the new marketeer? There involvement in campaigns is becoming far more influential as everybody tries to make the adverts king of prime time TV with there show stoppers. It has also made me to look into the Fluxus movement which is latin for 'to flow', this is basically what happens in all of the T-Mobile adverts and campaigns. The involvement of composers is becoming and more and more so are marketeers going to be needed in the future??? Hmmm....
