in an homage to the beatles' experimentation with reversed tracks (and those rumoured), the "reunion" track "free as a bird" featured a backward message that sounds like "made by john lennon." this is only a coincidence, and the phrase that was reversed to achieve this was "turned out nice again" (a catchphrase of george formby; george harrison was a great formby fan). the beatles-inspired cirque du soleil show "love" included the song "gnik nus," which was the vocal track to "sun king" played in reverse, which was accidentally created when giles martin (george martin's son) flipped the cymbal from "sun king" for an effect used on the "within you without you / tomorrow never knows" mashup and discovered he'd also flipped the vocal track. also, the mashup track "within you without you / tomorrow never knows" uses reversed cymbals, as well as reversing one of the tamboura riffs from "within you without you."
