Engelbert Humperdinck (born Arnold George Dorsey; 2 May 1936) is an English pop singer, best known for his UK number-one hits "Release Me" and "The Last Waltz", as well as "After the Lovin'" and "A Man Without Love".

Born in Madras, India, Dorsey moved to Leicester, England, as a child with his family, where he took an early interest in music. Initially playing the saxophone in nightclubs, he soon started singing, releasing his first single, "I'll Never Fall in Love Again", in 1958. After struggling with tuberculosis, in the mid-1960s Dorsey returned to his musical career, adopting the stage name "Engelbert Humperdinck" after the German 19th-century composer of operas. Signed to Decca Records, he gained early success in Belgium after representing England in the 1966 Knokke song contest there. On his return, he released a string of singles that proved commercially successful, both domestically and in the United States. Gaining a devoted fan following, he also fronted a short-lived television series, The Engelbert Humperdinck Show.
