  We identify 34 highly-probable detached, red giant eclipsing binary pairs
among 315 candidates in Devor's catalog of $\sim$10,000 OGLE-II eclipsing
binaries. We estimate that there should be at least 200 such systems in
OGLE-III. We show that spectroscopic measurements of the metallicities and
radial-velocity-derived masses of these systems would independently constrain
both the age-metallicity and helium-metallicity relations of the Galactic
Bulge, potentially breaking the age-helium degeneracy that currently limits our
ability to characterize the Bulge stellar population. Mass and metallicity
measurements alone would be sufficient to immediately validate or falsify
recent claims about the age and helium abundance of the Bulge. A spectroscopic
survey of these systems would constrain models of Milky Way assembly, as well
as provide significant auxiliary science on research questions such as mass
loss on the red giant branch. We discuss the theoretical uncertainties in
stellar evolution models that would need to be accounted for to maximize the
scientific yield.
