Irwin Goodman (real name: Antti Yrjö Hammarberg, 14 September 1943, Hämeenlinna – 14 January 1991, Hamina) was a popular Finnish rock and folk singer. In the late 1960s he was widely known as a protest singer. He recorded over 300 songs, most of which were his own compositions, with lyrics written by Vexi Salmi. Irwin Goodman started as a protest song singer in the folk boom of the mid-1960s, his humorous songs, often mocking the authorities, became favorites of the Finnish people; to such extent that small "Irwin singalike" contests are continuously arranged by some pubs for entertainment. Goodman had continuing troubles with Finnish tax authorities and had ever-worsening problems with alcohol. His escapades were eagerly followed by sensationalist magazines such as Hymy.
