"Lady Willpower" is a song written by Jerry Fuller and recorded by Gary Puckett & The Union Gap for their 1968 album, Incredible. It is sung from the point of view of a man who is frustrated that the woman he is seeing will not agree to have sex with him. He promises, if she complies, to "shower [her] heart with tenderness," but it is also implicit that the relationship will end ("It's now or never") if she does not. The song hit #1 on the Cash Box Top 100 and #2 on the Billboard Hot 100 in 1968. It also reached #5 on the UK Singles Chart during the year.
