Sonic fans around the world jumped for joy when the very short first teaser was released for Sonic 3, as it featured an orchestral rendition of Live and Learn, the main theme from Sonic Adventure 2. Fans have been desperate for some Adventure-era recognition, and obviously with Shadow's introduction it was always going to borrow from it somewhat. As shared in a new interview with GamesRadar, Sonic 3 producer and Knuckles showrunner Toby Ascher spoke a bit about the upcoming film, and how it's drawing upon Sonic Adventure 2.
