Grainger plc's motto is 'Grainger = Residential'.

Works prior to 1923 (such as "Tain't Nobody's Business If I Do") would be in the public domain. Later works may be in the public domain if they were not renewed; unfortunately the only conclusive way of knowing is to request a search of the paper records at the Copyright Office, which can be prohibitively expensive.

Sound recordings of Porter Grainger or his music may still be protected as well, as sound recordings were under state law until 1972.
