Williams formed the group with William Brown, Julius Green and Robert Phillips in Memphis and recorded on Stax Record’s Volt label. With Williams’ high tenor voice and the group’s soft soul harmonies, The Mad Lads had several songs on the Billboard R&B chart in the 1960s, including “I Want a Girl” and “By the Time I Get to Phoenix.”

In the middle of his recording career, Williams was drafted into military service and served in the Vietnam War. Williams also recorded as a solo artist in the 1970s.
