Karl Denver was a Scottish singer, who, with his trio had a series of UK hit singles in the early 1960s. Most famous of these was a 1961 version of "Wimoweh", which showed off Denver's falsetto yodelling register. He reached the Top 20 with his first five yodel-based singles.

"The Lion Sleeps Tonight" is a song originally written and first recorded in 1939 by Solomon Linda under the title "Mbube", through South African Gallo Record Company. Lyrics of Linda's original version were written in Zulu, while those of the English one were later written by George David Weiss.
