If You Wanna Be Happy

"If You Wanna Be Happy" is based on the song "Ugly Woman" by the Trinidadian calypsonian Roaring Lion (writing credited to his real name, Rafael de Leon), recorded in 1934. It hit #1 on the Hot 100 on May 18, 1963, as well as on the R&B singles chart.[1] It was issued on Frank Guida's S.P.Q.R. label[2] and distributed by London Records, and in the United Kingdom on EMI's Stateside label.

The original single lists a running time of 2:14; some later releases are slightly longer due to an extended fade-out.

Towards the end of the track, a brief dialogue takes place between Soul and a backup singer, based on Bo Diddley's song "Say Man": "Say Man!!"/ "Hey baby."/ "I saw your wife the other day."/ "Yeah??"/ "Yeah, and she's ugly-y-y-y-y!!!"/ "Yeah, she's ugly, but she sure can cook, baby."/ "Yeah, alright."/ Soul's counterpoint melody in a falsetto is heard as the song fades out.
