Which 1974 George McCrae single is often credited as an early international disco hit?

George McCrae’s 1974 single “Rock Your Baby” is often credited as an early international disco hit.

The song was written and produced by Harry Wayne Casey and Richard Finch of KC and the Sunshine Band. McCrae recorded the lead vocal after the planned female vocalist could not attend the session, and the track became a major success.

“Rock Your Baby” reached number one in several countries, including the United Kingdom, Australia, and the United States. Its prominent four-on-the-floor rhythm, electronic keyboard textures, and polished Miami soul production helped define the emerging disco sound.

It is sometimes described as the first disco song to become a worldwide pop hit, although “disco” developed from several overlapping soul, funk, and club-music traditions. The song’s importance is therefore best understood as an early breakthrough rather than a universally agreed single “first.”
