Lester Square (born Thomas Woodburne Bruce Hardy, April 17, 1954, Canada) is the Canadian lead guitarist for The Monochrome Set. He also sings backing vocals, designed some of the band's record sleeves, and co-wrote some of their music. He had previously been in the original Adam and the Ants, (and its earlier incarnation known as The B-Sides), writing "Fall In" and "Fat Fun" during this period. He left in 1978 to form The Monochrome Set with singer-songwriter Bid, a band cited as "a major influence on the Smiths, Franz Ferdinand, Orange Juice, Fire Engines and a whole host of UK indie and post punk bands." He has also briefly played guitar with The Invisible (1985-1987), ...And the Native Hipsters, plus Jesus Couldn't Drum.
Square also composed music for dance performance, most notably Rhythm and Hues, a kinaesthetic exploration of 20th century works of art in collaboration with the Tate Gallery and Helen McCookerybook. Also in collaboration with McCookerybook, he composed soundtrack music for the Channel 4 documentaries Pictures of Women and No-one Likes Us, We Don't Care, Akiko Hada and Wolfgang Müller's 1991 parable on the fall of the Berlin Wall, The Fall of a Queen, or the Taste of the Fruit to Come.
