Jeffrey Hammond

Jeffrey Hammond (born 30 July 1946), often known by his former stage name Jeffrey Hammond-Hammond, is an English artist and former musician best known for being the bassist of progressive rock band Jethro Tull from 1971 to 1975. With Jethro Tull, Hammond played on some of the band's most successful and well-known albums, including ''Aqualung'' (1971) and ''Thick as a Brick'' (1972).

Hammond adopted the name "Hammond-Hammond" as a joke, since both his father's surname and mother's maiden name were the same. He also joked in interviews that his mother defiantly chose to keep her maiden name, just like Eleanor Roosevelt. Provided by Wikipedia
