Much of the material for Leader of the Pack such as "Bull Dog" and "It's Easier To Cry" emphasized their new style. Other songs on the album include cover versions of "Maybe" originally by The Chantels with Betty Weiss on lead vocals, along with "Shout" by The Isley Brothers and "Twist and Shout" by the Top Notes. Also on the album is "Give Him A Great Big Kiss" which The Shangri-Las would release as a single later in the year. Although the group had scored two major hits, the album only charted at 109 on the U.S. albums chart.
"Leader of the Pack" (Morton, Jeff Barry, Ellie Greenwich) Motorcycle sound effect provided by engineer Joe Venneri former original band member of the Tokens. Joe cruised up a flight of stairs on his motorcycle during a live recording adding a classic touch to the hit song.
