The first American single for the brothers from Australia led them into the spotlight: How Can You Mend a Broken Heart by The Bee Gees.
In 1970, brothers Barry and Robin Gibb worked on the song, along with another song Lonely Days, both developed after a period of time when they were separated.
Along with brother Maurice, the trio finished the two songs, which would be on their new studio album Trafalgar.
The first part of the song was sung by Robin, then Barry and then the three harmonize on the chorus with their distinctive vocal sound.
The song was recorded in London in January 1971 and was the first single released from Trafalgar on Polydor Records.
The song was released on May 28, 1971 and although failed to attract attention on the UK charts, steadily climbed the Billboard Hot 100 in the US, and became the band’s first number one hit in America.
The single also charted in the top five on the Billboard Adult Contemporary Chart. The song was nominated in 1972 for the Grammy for Best Vocal Performance by a Duo, Group or Chorus.
And the song has been a fan favourite since the 1970s, and was covered by fellow singers including Cher, Johnny Mathis and Al Green.
