Israel's national anthem, "Hatikva," has been incorporated into a new anthem, albeit it both informal and for a fictitious world.

Israeli singer-songwriter Michael Greilsammer recently released a mashup melding the song composed by Samuel Cohen in 1888 with the opening theme music from the hit HBO series "Game of Thrones," according to The Hollywood Reporter.

"Right after watching the last episode of 'Game of Thrones' I got a call regarding my concerts in France for Israel's Independence Day," Greilsammer reportedly said. "They asked for a promo video, at that moment I got the idea to do this."
Greilsammer thereafter released his mashup version, which he performed with Uriel Sverdin and Shimrit Greilsammer, on YouTube. The video, filmed in black and white, already has over 40,000 hits since being uploaded April 23.

Greilshammer released his debut album in 2009 and often plays abroad in countries such as the United Kingdom, France, Germany and Canada, according to The Hollywood Reporter. In 2009, he joined other local musicians, including folk rock singer Alma Zohar, to sing with foreign workers' children at a kindergarten in south Tel Aviv to protest the planned deportation of hundreds of children of foreign laborers.
