'Happiness Is Dean Martin' was released in 1967 by Reprise Records, also produced by Jimmy Bowen. The title references the popular phrase 'Happiness Is...', and the album maintains the contemporary pop focus of its predecessor.
The album includes covers of hit songs such as 'Everybody Loves Somebody' (though this version differs from his 1964 hit) and 'The Green, Green Grass of Home'. It reached number 131 on the Billboard 200 chart.
Recorded at Reprise Studios in Los Angeles, the album featured arrangements by Ernie Freeman and other session musicians. Although not a major commercial success, it reflects Martin's phase of trying to connect with younger audiences.
