"Relax Your Mind" featuring Faith Evans, is the second single by R&B vocal group Boyz II Men from the album "Full Circle".
 This was the last single that included bass singer, Michael McCary.
"Farewell My Love" is a 1963 single by The Temptations for the Gordy (Motown) label.
 It was the last single that was written and produced by Motown president Berry Gordy for well over a decade, and the last released during the period of the "Original 5" lineup (before member Elbridge "Al" Bryant was fired).
 It is also noted as the group's last single to miss the "Billboard" pop chart's Top 40 until 1971's "It's Summer" (and the last to not make it on any U.S. music charts for the next 23 years).
 Up until now the group was jokingly referred to at this time as the "Hitless Temptations" by the Motown staff, much like their "sister" group, The Supremes, were called the "no-hit Supremes".
 However, their next single, the Smokey Robinson-produced "The Way You Do the Things You Do", would reach the Top 20 of the U.S. pop chart, breaking the group's streak of being "hitless".
"Bend and Break" is a song performed and composed by English rock band Keane, released as the fifth and last single from their debut album "Hopes and Fears".
 This single was released only in some European countries (not in the United Kingdom) such as Germany and Austria, similarly to their 2007 single "Try Again".
 However "Bend and Break" was still heard on some American radio stations.
 The single features "Bend and Break", "On a Day Like Today" and a live version of "Allemande", as well as the "Bend and Break" live videoclip.
 "Bend and Break" is drummer Richard Hughes' favourite Keane song.
 This was also the last single that used the typeface "Cochin", the one used in the "Hopes and Fears" era.
Nationality is a legal relationship between an individual person and a state.
 Nationality affords the state jurisdiction over the person and affords the person the protection of the state.
 What these rights and duties are vary from state to state.
Romani people (Czech: "Romové" , commonly known as Gypsies Czech: "Cikáni" ) in the Czech Republic constitute a minority.
 According to the last census from 2011, the Romani nationality was reported by the total of 13,150 inhabitants.
 Only a small part of them filled in only the Romani nationality (5 199).
 Most of them stated the Romani nationality in combination with another one, for example, the Romani and Czech, the Romani and Moravian and the like (7,951).
 In the 2001 Census, 11,746 people reported the Romani nationality – at that time it was 0.1% of those claiming some nationality.
 In 2011, the result 13,150 is 0.2% of those, who reported some nationality.
Multiple citizenship, also called dual citizenship or multiple nationality or dual nationality, is a person's citizenship status, in which a person is concurrently regarded as a citizen of more than one state under the laws of those states.
 There is no international convention which determines the nationality or citizen status of a person, which is defined exclusively by national laws, which vary and can be inconsistent with each other.
 Multiple citizenship arises because different countries use different, and not necessarily mutually exclusive, criteria for citizenship.
 Colloquial speech refers to people "holding" multiple citizenship but technically each nation makes a claim that this person be considered its national.
