Former Styx frontman Dennis DeYoung is putting the finishing touches on what he describes as his 'final' album. In doing so, he's reached out to Julian Lennon to help sing harmonies and backing vocals on a song called "Good Old Days." As you can see from Lennon's Instagram post above... and DeYoung's Facebook post below, the two seemed to hit it off. DeYoung confesses he wanted to embrace his Beatles influences on this album, so why not go as close the source as possible! No release date has been set for the album yet. Stay tuned!
