"Love Potion No. 9" is a song written in 1959 by Jerry Leiber and Mike Stoller. It was originally performed by the Clovers, who took it to number 23 on the US as well as R&B charts that year. The "kissing a cop" lyric led to the song being banned by some radio stations. The lyrics also have the narrator describe himself as being "a flop with chicks since 1956"; later recordings of the song have often changed the year to suit the year of recording or the age of the performer.
