I'm going on my first ever ocean-going cruise in January - Panama Canal full transit on the Coral Princess.  I've started reading up about what's on offer on the ship, and The Voice of The Ocean caught my eye.  I'm an amateur singer and love a Karaoke, and really want to enter.  Can anyone tell me about how it all works?  How many people enter the Karaoke tryouts? How many get through to the show? What's the standard like?    Any info from personal experience greatly appreciated.
