Chicago as a band has ceased to exist. I think they have become like a high school band with a constantly revolving door of new people. I believe there is only one original member in the line up these days ! Certainly nobody left that wrote all these tunes !
Robert Lamm, who wrote and sang this song in 1969, is the one singing it in this video and is still in the band. The trombone and trumpet players are also originals.
