The things you can fix with technology...
I just found this story on Digg about a new form of music editing software that gives you pretty much absolute control over the notes in a recording. Their reported example was the ability to simply correct a wrongly played note of an instrument within a recorded orchestra performance.
With this stuff it may even be possible to make our schools kids music projects bearable to listen to, may..
There is a nice demonstration video of it in action in the story added below:
