The single was released in the wake of the band's high-profile performance at Woodstock, which greatly expanded their fanbase. The song peaked at number 2 on the U.S. Billboard Hot 100 pop singles chart and number 3 on the U.S. Billboard soul singles chart in autumn 1969.

The track was covered by The Beach Boys on their commercially and critically disastrous 1992 album Summer in Paradise. A video was made to accompany the song.

Genesis vocalist and drummer Phil Collins cited the song as one of the musical inspirations for "Misunderstanding". The members of Toto have also cited it as an inspiration for "Hold the Line".

Rolling Stone ranked it #247 on their list of the 500 Greatest Songs of All Time.

#2 in 1969, how about today?
