The abundances of C, N, O and the C and O isotopic ratios of stars undergoing the first dredge up phase of convective mixing are summarized in this paper. It is shown that rough agreement between predictions and observations of the surface abundances may be achieved for young Pop I giants, but that the observations deviate increasingly from the predictions in old disk field giants and especially in Pop II field and globular cluster giants. Recent investigations containing new information on the correlations among these elements in globular cluster giants are discussed.
