Who are the band members currently touring with Chicago?

As of my last update, the band Chicago's touring lineup typically includes founding members Robert Lamm and James Pankow, along with long-time members Lee Loughnane, Walt Parazaider, and Jason Scheff. Other musicians frequently involved in their tours include Tris Imboden on drums, and Neil Donell and Ramon Ortiz as vocalists and Guitarists. However, lineup changes can occur, so it's best to check their official website or recent announcements for the most current information.
