Some context: Beccy Cole (born Rebecca Diane Thompson, 27 October 1972), also known as Beccy Sturtzel and Rebecca Diane Albeck, is an Australian country music singer-songwriter and multi-instrumentalist. She has released eight albums, with three reaching the ARIA Albums Chart top 40, Little Victories (20 January 2003), Preloved (3 September 2010) and Songs & Pictures (30 September 2011). Her video album, Just a Girl Singer, peaked at No. 6 on the ARIA Top 40 DVD Chart in August 2004. Cole has received nine Golden Guitar trophies at the CMAA Country Music Awards of Australia.
During the festive season of December 2005 and January 2006, Cole joined the Tour de Force series of concerts in Iraq and "across the Middle East" for Australian Defence Force "personnel serving in Operation Catalyst". Also performing at the concerts were Little Pattie (patron of Forces Advisory Council on Entertainment, which organised the tour's entertainers), Angry Anderson, Bessie Bardot, Hayley Jenson, and comedian Lehmo. They were backed by the Royal Australian Navy Band. Anderson later recalled "[Cole] struck me from the beginning, I mean she's a born entertainer, and I thought, this chick is as funny as hell. The songs that she was singing, original tunes, and just funny and witty".  Upon return to Australia Cole received a letter from a disgruntled former fan who objected to her Tour de Force appearances and declared "I've taken your poster off of my wall and I won't be listening to your music any more". In May 2006 she issued a single, "Poster Girl (Wrong Side of the World)" in response, she declared her support for the Australian diggers but not the Iraq War. Also that month she re-released Feel This Free, with bonus tracks, on Warner Records. In January the following year, at the 35th Country Music Awards of Australia, she received three Golden Guitar trophies for Female Artist of the Year, Single of the Year, and Song of the Year for "Poster Girl (Wrong Side of the World)". On 17 March 2007 Cole appeared on celebrity quiz show, RocKwiz, she performed "Rockabilly Fever" and a duet with Mark Lizotte on "A Good Year for the Roses".  On 12 October 2007 Cole issued her debut live album, Live @ Lizotte's, with guest appearances by Chambers, Jeffreys and Sara Storer. The deluxe version included a DVD of seven live performances and a Behind the Scenes documentary. In 2007, Cole, Jeffreys and Storer combined to form Songbirds. A live concert film Songbirds: You've Got a Friend was recorded at the Tamworth Country Music Festival on 22 January 2009 and the related DVD was released in May by EMI Music Australia. The DVD went gold in 2009. Susan Jarvis of Capital News noted that the "friendship between the three girls is very much in evidence" where each "performs some of their songs solo, but the three come and go in a wonderfully fluid and organic way, providing a feeling of warmth and spontaneity".

Some context: Vlachs (English:  or , or rarely ) is a historical term and exonym used for the Eastern Romance-speaking peoples especially in the Balkans. The term also became a synonym in the Balkans for the social category of shepherds, and was also used for non-Romance-speaking peoples, in recent times in the western Balkans derogatively. Apart from the Romanians and Moldovans, there are indigenous Romance-speaking groups in Greece, Albania and Macedonia, such as the Aromanians and Megleno-Romanians. "Vlachs" were initially identified and described during the 11th century by George Kedrenos.
The word "Vlach" is etymologically derived from the ethnonym of a Celtic tribe, adopted into Proto-Germanic *Walhaz which meant "stranger", from *Wolka- (Caesar's Latin: Volcae, Strabo and Ptolemy's Greek: Ouolkai).  Via Latin, in Gothic, as *walhs, the ethnonym took on the meaning "foreigner" or "Romance-speaker", and was adopted into Greek Vlahi (Blakhoi), Slavic Vlah, Hungarian olah and olasz, etc. The root word was notably adopted in Germanic for Wales and Walloon (German: Welsch), and in Poland Wlochy became an exonym for Italians. Via both Germanic and Latin, the term started to signify "stranger, foreigner" also in the Balkans, where it in its early form was used for Romance-speakers, but the term eventually took on the meaning of "shepherd, nomad". The Romance-speaking communities themselves however used the endonym (they called themselves) "Romans". During the early history of the Ottoman Empire in the Balkans, there was a social class of Vlachs in Serbia and Macedonia, made up of Christians who served as auxiliary forces and had the same rights as Muslims. In Croatia, the term became derogatory, and Vlasi was used for the ethnic Serb community.  Romanian scholars have suggested that the term Vlach appeared for the first time in the Eastern Roman Empire and was subsequently spread to the Germanic- and then Slavic-speaking worlds through the Norsemen (possibly by Varangians), who were in trade and military contact with Byzantium during the early Middle Ages (see also Blakumen).  The term "Vlach" is used in scholarship for the Romance-speaking communities in the Balkans, especially those in Greece, Albania and Macedonia.
