Hilarious in Hindsight: The 2003 DVD release of PopArt has commentary for each music video. During the commentary for "Liberation", this exchange occurs:
Chris Lowe: Looks kind of sexual, doesn't it?
Neil: I think it's just psychedelic.
Chris Heath: Doesn't everything mean something?
Neil: Oh, I don't think so.
- This became particularly funny in 2012, after the Pet Shop Boys released an entire song called "Everything Means Something" on Elysium.
