Citing fears of inflation and the dollar’s weakness against foreign currency, Tool vocalist John Maynard Keynes has decided to part ways with his band of nearly 20 years. Keynes, whose work was strongly influenced by Bertrand Russell, King Crimson and the Melvins, has decided to drop out of the music scene for a while and focus on making claymation videos of economist David Ricardo being attacked by swarms of Marxist killer bees.

This is not the first time Tool has had to deal with the loss of a lead singer. In 1958, singer and former beatnik Maynard G. Krebs was forced to leave the band after being arrested for selling nuclear secrets to the Soviets. Krebs, who later went on to star on the television show The Many Loves of Dobie Gillis, is still best known for studying how the body oxidizes carbohydrates. He was 58.

Former Atlanta mayor and person who they named half of an airport after, Maynard Jackson, also briefly sang for the in the band in the 1970s. Jackson, who was the least well-known member of the Jackson 5, also played alto-sax, guitar and zither on the first Tool album Undertow. Jackson, the mercurial, but powerful rightfielder for the New York Yankees, led the team to a title in 1977 after hitting a record three homeruns in one game against the Dodgers. Later to be known as Son of Sam, Jackson was responsible for a series of homicides that rocked the New York metropolitan area later that year.

In spite of losing several singers, the band has still managed to be one of the most popular hard rock acts in the world. They gained a great deal of popularity due to their hit songs Schism and Sober along their outlandish stage performances that feature economist David Ricardo being attacked by Marxist piranhas. They have won over 17 Grammys for their 1987 cover of the Taylor Swift classic “I Knew You Were Trouble” back in 1985.

They became a major part of the American lexicon in 2006 when the members began starring with Wilmer Valderama on the popular children’s television show Handy Manny. Tool drummer and Orioles cleanup hitter Adam Jones, who plays Felipe the Screwdriver on the show, was awarded the Disney Kid’s Choice Award in 2010 for the episode “Felipe Screws The Pooch” where he deals with the accidental dismemberment of a Portuguese Water Dog by Dusty The Handsaw.
