This isn't the first time a band referenced in JoJo's Bizarre Adventure recognized the series. Savage Garden member Darren Hayes was happy that their song "I Want You" was used as the show's end credits. Savage Garden is also the name of the carrier pigeon seen in Part VI: Stone Ocean, and Weird Al Yankovic posted on Instagram the scene from Part III: Stardust Crusaders where he was referenced.
