question:
The Selective Service System is an independent agency of the United States government that maintains information on those potentially subject to military conscription. Virtually all male U.S. citizens and male immigrant non-citizens between the ages of 18 and 25 are required by law to have registered within 30 days of their 18th birthdays and must notify Selective Service within ten days of any changes to any of the information they provided on their registration cards, like a change of address. A 2010 Government Accountability Office report estimated the registration rate at 92% with the names and addresses of over 16.2 million men on file. However, the only audit of the addresses of registrants on file with the Selective Service System, in 1982, found that 20 -- 40% of the addresses on file with the Selective Service System for registrants in the age groups that would be drafted first were already outdated, and up to 75% for those registrants in their last year of potential eligibility to be drafted would be invalid.
answer:
when do you need to sign up for selective service

question:
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.
answer:
who owns the copyright to the happy birthday song
