  We present near-IR spectroscopy of three Extremely Red Objects (EROs) using
the OHS/CISCO spectrograph at Subaru telescope. One target exhibits a strong
emission line which we identify as H-alpha at z = 1.34. Using new and existing
ground-based optical and near-IR imaging, and archival HST imaging, we argue
that this target is essentially an elliptical galaxy, with an old stellar
population of around 4E11 solar masses, but having a dust-enshrouded
star-forming component with a SFR of some 50--100 solar masses per yr. There is
no evidence that the galaxy contains an AGN. Analysis of a further two targets,
which do not exhibit any features in our near-IR spectra, suggests that one is
a quiescent galaxy in the redshift range 1.2 < z < 1.6, but that the other
cannot be conclusively categorised as either star-forming or quiescent.
  Even though our first target has many of the properties of an old elliptical,
the ongoing star formation means that it cannot have formed_all_ of its stellar
population at high redshift. While we cannot infer any robust values for the
star formation rate in ellipticals at z > 1 from this one object, we argue that
the presence of an object with such a high SFR in such a small sample suggests
that a non-negligible fraction of the elliptical galaxy population may have
formed a component of their stellar population at redshifts z ~ 1--2. We
suggest that this is evidence for ongoing star formation in the history of
elliptical galaxies.
