On July 8 Robey wrote to Phillips again, thanking him "kindly for your co-operation in this matter", but Phillips still refused to purchase a mechanical license for Thomas' "Bear Cat". Robey then instructed his company lawyer Irving Marcus to sue Phillips and Sun Records, hoping to use this as a test case to determine the legal status of all answer songs. While earlier pressings of Sun 181 bore the caption "(The Answer To Hound Dog)" above the A-side title, as a result of the legal action this was removed from all later pressings. In the 1980s, Sam Phillips conceded: "I should have known better. The melody was exactly the same as theirs, but we claimed the credit for writing the damn thing".
