"Just Because" was copyrighted by the Shelton Brothers and Sid Robin in the mid 1930s, when the Shelton Brothers first recorded this song under their own name. The same song, however, was recorded by Nelstone's Hawaiians in the late 1920s and by the Lone Star Cowboys in 1933.
In 1948 the Peer International Corporation sued Leeds Music and Columbia records alleging infringement on the Shelton/Shelton/Robin composition, but with the defendants arguing “that the music had been in the public domain prior to Touchstone’s and Nelson’s writing, and that the latter had copied and appropriated substantial portions of their version from prior copyrights.” It's unclear in favour of whom the court eventually ruled.
