This song is titled “Nothing Happened” and it was done entirely in Logic, not at all in GarageBand. I still have a bit to learn when using Logic. (Most of the time I record in Logic and do everything else in GarageBand.) You should be able to hear it right on this page, using the embedded player below.
You can grab it from Ourmedia or the Internet Archive, and it’s got a Creative Commons Attribution License. (If you need something else, get in touch with me.)
