Fans knew of the song in some form before its reveal as its lyrics and melody were typically quoted during live performances of “Shanghai,” with appearances as far back as 2023-03-11. These lyrics weren’t always the same with Stu emphasizing certain lines depending on the performance, as well as some goofier lines which showcased a playful energy, but they became a notable and reliable part of the track continuing into the following year.
While there had been some speculation that these were part of a bigger song, theories started up again as the band began to tour America in 2024. At these shows, Stu settled on a heartfelt passage with lyrics taking specific placements compared to prior performances. However Gizzard also expanded the song by adding new lyrics from Joey and Ambrose. During a performance of “Hot Water” on 2024-08-27 they showcased Joey’s section while Ambrose’s passage was briefly quoted. These verses weren’t always included however, as “Shanghai” on 2024-11-08 contained Stu and Joey’s verses but not Ambrose’s section. “Grow Wings and Fly…” wouldn’t seen any sort of official documentation until the band’s marathon show at the Germania Insurance Amphitheater in Austin on 2024-11-15. During a performance of “Shanghai,” Stu and Joey switched to guitar to jam with Stu providing the lyrics before Joey’s verse, which led to Ambrose’s section returning. After the show fans got a hold of the setlist which noted the lyrics as part of a completely separate track, something which is not done for any other songs that the band may quote within their shows. It was also separated from “Shanghai” when the show was released as Live in Austin ‘24.
