Input: Consider Input: None of the early appearances of the 'Happy Birthday to You' lyrics included credits or copyright notices. The Summy Company registered a copyright in 1935, crediting authors Preston Ware Orem and Mrs. R. R. Forman. In 1988, Warner / Chappell Music purchased the company owning the copyright for US $25 million, with the value of 'Happy Birthday' estimated at US $5 million. Based on the 1935 copyright registration, Warner claimed that the United States copyright will not expire until 2030, and that unauthorized public performances of the song are illegal unless royalties are paid to Warner. In one specific instance in February 2010, these royalties were said to amount to US $700. By one estimate, the song is the highest-earning single song in history, with estimated earnings since its creation of US $50 million. In the European Union, the copyright for the song expired on January 1, 2017.

Output: who owns the copyright to the happy birthday song

Input: Consider Input: In the United States, the President can issue an executive order for the flag of the United States to be flown at half-staff upon the death of principal figures of the United States government and others, as a mark of respect to their memory. When such an order is issued, all government buildings, offices, public schools, and military bases are to fly their flags at half-staff. Under federal law (4 U.S.C. 7 (f)), the flags of states, cities, localities, and pennants of societies, shall never be placed above the flag of the United States; thus, all other flags also fly at half-staff when the U.S. flag has been ordered to fly at half-staff. There is no penalty for failure to comply with the above law as to enforce such a penalty would violate the First Amendment.
Output: when does the flag at the white house fly at half mast
