Well, here's "Fight Song", which is one of her favorite songs. Let's grab the clip and load it up as a scratch track. I set up Julie and recorded her in one take singing along to the original.
Now, let's take the original clip and remove the vocals, paste it back into Cubase, and mix against *that*.
There we go. Gretchen beat me over the head until I got the EQ and reverb straightened out and now it sounds remarkably like Julie.
And pretty darn good for an eleven year old.
Here it is: Fight Song.
