The BBC says that it's recovered the earliest computer music ever recorded, renditions of Baa Baa Black Sheep and In the Mood from more than half a century ago.
The songs were captured by the BBC in the Autumn of 1951 during a visit to the University of Manchester.
The recording has been unveiled as part of the 60th Anniversary of "Baby", the forerunner of all modern computers.
The tunes were played on a Ferranti Mark 1 computer, a commercial version of the Baby Machine.
The Beeb thinks it now hold a record previously attributed to IBM and Bell Labs, for a recording made in 1957.
