This was written by Barry and Robin Gibb of the Bee Gees and first released on their 1967 international debut album Bee Gees 1st. As a single it reached No 17 in the United States and No 41 in the UK.
Nina Simone released it in 1969 and it reached No 5 in Britain.
If you want to see a decent song ruined beyond repair, here is Janis Joplin. This is a live version of the track on her 1969 album I Got Dem Ol’ Kozmic Blues Again Mama! However if you like music, give it a miss.
