"He Ain't Heavy, He's My Brother" is a ballad written by Bobby Scott and Bob Russell. Originally recorded by Kelly Gordon in 1969, the song became a worldwide hit for the Hollies later that year and also a hit for Neil Diamond in 1970. It has been recorded by many artists in subsequent years. The Hollies' version was re-released in 1988 and again was a major hit in the UK.

The Hollies are an English rock and pop band formed in 1962. One of the leading British groups of the 1960s and into the mid-1970s, they are known for their distinctive three-part vocal harmony style. Allan Clarke and Graham Nash founded the band as a Merseybeat-type group in Manchester, although some of the band members came from towns further north, in east Lancashire. Nash left the group in 1968 to form Crosby, Stills & Nash, though he has reunited with the Hollies on occasion.
