Ian Scott Anderson MBE (born 10 August 1947) is a Scottish-born musician, singer, songwriter and multi-instrumentalist best known for his work as the lead vocalist, flautist and acoustic guitarist of British rock band Jethro Tull. Anderson plays several other musical instruments, including keyboards, bass guitar, bouzouki, balalaika, saxophone, harmonica, and a variety of whistles. His solo work began with the 1983 album Walk into Light, and since then he has released another five works, including the sequel to the Jethro Tull album Thick as a Brick (1972) in 2012, entitled Thick as a Brick 2. Ian Anderson was born in Dunfermline, Fife, Scotland, the youngest of three brothers. His father, James Anderson, ran the RSA Boiler Fluid Company in East Port, Dunfermline. Anderson spent the first part of his childhood in Edinburgh.

In 1963, he formed The Blades from among school friends: Michael Stephens (guitar), John Evan (keyboards), Jeffrey Hammond (bass) and Barriemore Barlow (drums). This was a soul and bluesband, with Anderson on vocals and harmonica – he had yet to take up the flute. They played their first show at the Holy Family Church Hall in North Shore.

In late 1967, Anderson was still holding down a day job, namely cleaning the Ritz Cinema in Luton, including the toilets, in the mornings, “which took me half the day” he said in a later interview. He took an old, chipped urinal from the cinema storeroom and had it for a time after leaving the job. It was not, however, the urinal which “was bolted to the side of John Evan’s Hammond organ on stage” and figured in early 1970s Tull performances.

At this time Anderson abandoned his ambition to play electric guitar, allegedly because he felt he would never be “as good as Eric Clapton“. As he himself tells it in the introduction to the video Nothing Is Easy: Live at the Isle of Wight 1970, he traded his electric guitar in for a flute which, after some weeks of practice, he found he could play fairly well in a rock and blues style. According to the sleeve notes for the first Tull album, This Was (1968), he had been playing the flute only a few months when the album was recorded. His guitar practice did not go to waste either, as he continued to play acoustic guitar, using it as a melodic and rhythmic instrument. As his career progressed, he added soprano saxophone, mandolin, keyboards and other instruments to his arsenal.

His tendency to stand on one leg while playing the flute came about by accident, as he had been inclined to stand on one leg while playing the harmonica, holding the microphone stand for balance. Anderson was known for his famous one-legged flute stance, and was once referred to as a “deranged flamingo” This stance is on many album covers of Jethro Tull. During a long stint at the Marquee Club, a journalist described him, wrongly, as standing on one leg to play the flute, when in fact he was originally playing the harmonica on one leg. He decided to live up to the reputation, albeit with some difficulty. His early attempts are visible in The Rolling Stones Rock and Roll Circus (1968) film appearance of Jethro Tull. This was referenced in the facetious liner notes for Thick as a Brick in a quote about “the one-legged pop flautist, Ian Anderson”.
