Now if the band actually stopped playing well in advance of the sinking (as alleged by one of the posters), I find it more likely that the violin was genuine. I can't see anyone throwing a violin on a lifeboat as the last thing off the ship.
Hmmm....maybe it was found by the Californian or one of the other rescue ships (does a violin float?) but if so it seems there would be less doubt about its authenticity.
You need to change your tagline like I had to...
It should be brought and then played 24/7 in front of the White House.
