LORELAI: Yes, you are, you’re all grown up and soon you’ll be going off into the world … And after you spread those wings and fly away, I won’t have the opportunity to give you this.
A possible reference to the 1977 song “Spread Your Wings” by English rock band Queen, from their album News of the World; the repeated line is, Spread your wings and fly away. The song was included on Queen’s 1979 live album, Live Killers. The single got to #34 in the UK, and was most popular in the Netherlands at #20. It wasn’t released as a single in North American, but the live version was the B-side to the 1979 song “Crazy Little Thing Called Love”, which went to #1 in the US.
