The Unusually Solar-Like Cluster M67

I give an overview of our spectroscopic work on the old open cluster M67 and what it may tell us about the origin of the Sun, the existence of terrestrial planets around solar twins and effects that change the surface composition of stars. I will argue that much remains to be learned from studies of stars in different environments (globular clusters, open clusters, associations).
