"6 Years of Boney M. Hits (Boney M. on 45)" is a greatest hits medley by Boney M., inspired by the success of the hit medleys by Stars on 45. Originally released on the B-side of the band's 1981 Christmas single "Little Drummer Boy", the single was flipped over in January 1982 with the medley as an A-side. While failing to chart in Germany, the medley reached #6 in the Spanish charts and was also an A-side release in France and Japan. The 12" version featured a faded version on the German pressing and an unfaded version on the French pressing, while the UK version (included on the B-side of their UK top 40 hit "We Kill the World") was extended with their Christmas chart-topper "Mary's Boy Child - Oh My Lord".
