Deleting a project in Garageband

You don't delete it in GB, you delete it like any other file - go to the Finder and drag it to the trash.

I'm lost.
I created some files last night to get familiar with GB. I didn't save the projects. But now when I open an existing GB song it shows the two test ones i created last night and they have disk space useage.
How do i delete them?
Drag and drop doesn't work.
Closed GB, looked in Finder (top left on toolbar, right?
Nothing at all there, unless I have to dig deeper to retrieve to drag and rop, but nothing about any type of files there.
I am brand new with my first mac and very confused on some of the most basic things like this.
Getting around in GB seems easy enough though.

I do need to delete files as I am sure I'll have lots of garageband files that will need to be deleted in the future.
Thanks.
