Vocalist Ian Anderson and bassist Glenn Cornick leave the John Evans Blues Band to form Jethro Tull, naming their group after the 18th century inventor of a number of farm implements. John Evan himself will later join them as Jethro Tull's keyboard player.
Unlikely as its success might have seemed at first, Tull brought something to the party that noone else had. They had a couple US#1s, ....and over 20 Tull albums made into to the UK top-30 , including this year and last year!
