Tony Iommi, one of the founders of Black Sabbath, was a member of Jethro Tull for two weeks in 1968. He played with them on The Rolling Stones' Rock 'n' Roll Circus special, which did not air because of poor performances, but was released on video in 1995.

Anderson learned to play the flute by listening to and imitating the music performed by jazz artist Roland Kirk. Asked by Uncut magazine why he took up the flute, Ian Anderson replied: "I decided to quit the guitar when I heard Eric Clapton in '66, early '67. I had a white Fender Stratocaster that I'd bought for £30 from Lemmy, when he was guitarist with Reverend Black And The Rocking Vicars. I part exchanged it for a flute and a Shure Unidyne 3 Mic."
Anderson added: "The flute was a whimsical moment of self-indulgence. I wanted to find something to play that wasn't a part of the rock scene at the time. It sat gathering dust for about six months until I finally coaxed a note out of it in December '67 and by February 1968, Jethro Tull was born."
Ian Anderson is a morning person. He said in our 2013 interview
: "I wake up early in the morning. It's always good. Sometimes I wake up in the middle of the night; in the middle of a period of sleep I'll suddenly wake up with an idea for a song or a line of music and run to the bathroom, scribble it down on a piece of paper, and leave it next to the toothpaste so I find it in the morning. But other times I just get up earlyish - 7 o'clock, whatever it might be - and try to be creative before the household awakes."
