“Eight Miles High”
Many radio stations banned this trippy song -- often referred to as the first psychedelic rock tune -- because it appeared to be about drug use. More than 40 years after the song's release, guitarist Roger McGuinn still maintained it was about the band's first flight to England. But band mate David Crosby told Rolling Stone it wasn't just about flying the friendly skies. "Of course it was a drug song," he said. "We were stoned when we wrote it. We can also justifiably say that it wasn't a drug song because it was written about the (plane) trip to London."
