Question: A song who's demo was leaked on to the internet on December 17th, 2014, was part of an album that was released on March 6th, 2015 by what record company?

"Illuminati" is a song recorded by American singer and songwriter Madonna for her thirteenth studio album "Rebel Heart" (2015).  It was written by Madonna Ciccone, Toby Gad, Maureen McDonald, Larry Griffin Jr., Mike Dean, Kanye West, Ernest Brown and Jacques Webster.  The song was produced by Madonna, West, Dean and Symbolyc One, with co-production by Charlie Heat and additional production by Travis Scott.  The song's demo was leaked to the internet in December 2014, with twelve other tracks from the album.  Its final version was released on December 20, 2014, with five other tracks on iTunes store as "an early Christmas gift" to avoid further leaks.  The song's demo version features dance synths and acoustic guitars; after showing the song to West, he felt connected to the song and changed it to a darker sound.  The song was conceived after Madonna was accused of being a member of the Illuminati; she wanted to write a song about who they really are and what they are not. <SEP> The 2/6th Battalion was an infantry battalion of the Australian Army that served during the Second World War.  Raised in October 1939 as part of the all volunteer Second Australian Imperial Force, the battalion formed part of the 6th Division and was among the first troops raised by Australia during the war.  Departing Australia in early 1940, the 2/6th were deployed to the Middle East where in January 1941, it took part in the first action of the war by Australian ground forces, the Battle of Bardia, which was followed by further actions around Tobruk.  Later, the 2/6th were dispatched to take part in the Battle of Greece, although their involvement in the campaign was short before they were evacuated.  Some members of the battalion also subsequently fought on Crete with a composite 17th Brigade battalion, and afterwards the battalion had to be re-formed in Palestine before being sent to Syria in 1941–42, where they formed part of the Allied occupation force that was established there in the aftermath of the Syria–Lebanon campaign. <SEP>  It was written by Madonna, Toby Gad, Maureen McDonald, Larry Griffin Jr., Chancelor Bennett, Dacoury Natche and Michael Tucker.
