Question: What countries signed the treaty that acknowledges Ireland's "traditional policy of military neutrality"? Passage:Ireland has been neutral in international relations since the 1930s. The nature of Irish neutrality has varied over time, and has been contested since the 1970s. Historically, the state was a "non-belligerent" in the Second World War (see Irish neutrality during World War II) and has never joined NATO, although during the Cold War it was anti-communist and aloof from the Non-Aligned Movement. The compatibility of neutrality with Ireland's membership of the European Union has been a point of debate in EU treaty referendum campaigns since the 1990s. The Seville Declarations on the Treaty of Nice acknowledge Ireland's "traditional policy of military neutrality", reflecting the narrow formulation of successive Irish governments. Others define Irish neutrality more broadly, as having "a strong normative focus, with a commitment to development, United Nations peacekeeping, human rights and disarmament".

Question: Who was the founder of the record company that signed Funkadelic? Passage:By 1970, the five Parliaments singers were touring with five backing musicians known separately as Funkadelic. The highly rehearsed performances and suited look of The Parliaments gave way to the members dressing in their own outrageous styles. Haskins wore long johns on stage. Due to the contractual issues surrounding the group name, Clinton signed the band as Funkadelic to Westbound Records. The ensemble released their first album Funkadelic in 1970. Clinton also renamed his group of singers Parliament (but still with the Funkadelic musicians as official members) and signed that act to the Holland-Dozier-Holland-owned record label, Invictus. Parliament released their first album Osmium in 1970. Clinton now had two groups that were actually one entity. Under the name Funkadelic, the ensemble was geared towards a rock audience, and as Parliament it was aimed at a soul music audience. Collectively, they became known as Parliament-Funkadelic, or P-Funk. Haskins contributed to P-Funk as a writer through 1972. He toured and appeared on P-Funk albums as a singer, and occasionally as a guitarist, throughout the 1970s. In June 1977 at the height of P-Funk's popularity, Haskins (along with other original Parliaments Calvin Simon and Grady Thomas) left the ensemble over financial and management disputes with Clinton.

Question: Is the co-founder of Ptacek's late 1970s band still alive? Passage:Ptacek was born in East Berlin to a family of Czech and German descent. His family fled East Germany for the United States when he was five years old. They eventually settled in Chicago, where young Ptacek was first exposed to blues music. He moved to Tucson in the early 1970s, where he began his own musical career, most often solo, but sometimes he plugged in and led a trio as Rainer & Das Combo. He co-founded Giant Sandworms with Howe Gelb in the late 1970s. When the band decided to move to New York and became Giant Sand, Ptacek opted to stay in Tucson to make sure that he would not disrupt his then-new family. Although he never became well known in the United States, he became more and more recognized in Europe. ZZ Top guitarist Billy Gibbons was so impressed with the singer-guitarist that he arranged to have Kurt Loder review Ptacek's "Mush Mind Blues" cassette in Rolling Stone. Ptacek later traveled to Houston at the invitation of Billy Gibbons to record at Gibbons' Gold Star Sound Services studio which saw release as "The Texas Tapes" meeting international attention and approval. Robert Plant, similarly impressed, flew Ptacek to England for the sessions for B-sides to supplement the singles from Fate of Nations.
