<P> During his last decade, Leary proclaimed that the "PC is the LSD of the 1990s"--"turn on, boot up, jack in" reworked the existing phrase to suggest joining the cyberdelic counterculture . </P> <P> The phrase was referenced in several songs of the time . Psychedelic rock band Strawberry Alarm Clock parodies the quote in their 1967 song "Incense and Peppermints", singing "Turn on, tune in, turn your eyes around" in one of the lines . Gil Scott - Heron criticised the concept in his 1970 poem and song The Revolution Will Not Be Televised, with the line "You will not be able to plug in, turn on and cop - out". </P> <P> The lyrics, "Turn on, tune in, drop out" are included verbatim in several songs: </P> <Ul> <Li> "Turn On, Tune In" by Threshold </Li> <Li> "DI - 1 - 9026" on the album Nail by Scraping Foetus Off the Wheel </Li> <Li> "Drop Out" by Infected Mushroom </Li> <Li> "Ever Increasing Circles" on the compilation album Wake Up and Smell the...Carcass by the band Carcass </Li> <Li> "Turn On Tune In Drop Out" by Cracker </Li> <Li> "Turn on, Tune in, Stay inert" in "Flash Delerium" by MGMT </Li> <Li> "Turn On / Tune In / Drop Out" on The Fugs' album Tenderness Junction </Li> <Li> "Tune In, Drop Out" in "Trigger Hippie" by Morcheeba </Li> </Ul>
