From the new merch drop at merch.devolverdigital.com, in case anyone doesn't know.

The only copyright information on the box itself is "Peanuts" and "United Feature Syndicate Inc." who owned the merchandising rights for a LONG time. We got it secondhand, so we don't have any info on its origin, either. I'd imagine the song would be relatively common, though, considering the sheer magnitude of music boxes that UFS pumped out.
