McCartney's LSD admission formalised the link between rock music and drugs, and attracted scorn from American religious leaders and conservatives. Vice-President Spiro Agnew contended that the "friends" referred to in "With a Little Help from My Friends" were "assorted drugs". As part of an escalating national debate that triggered an investigation by the US Congress, he launched a campaign in 1970 to address the issue of American youth being "brainwashed" into taking drugs through the music of the Beatles and other rock artists. In the UK, according to historian David Simonelli, the album's obvious drug allusions inspired a hierarchy within the youth movement for the first time, based on listeners' ability to "get" psychedelia and align with the elite notion of Romantic artistry. Harrison was eager to separate the message of "Within You Without You" from the LSD experience, telling an interviewer: "It's nothing to do with pills ... It's just in your own head, the realisation."
