  Asteroseismology of stellar clusters is potentially a powerful tool. The
assumption of a common age, distance, and chemical composition provides
constraints on each cluster member, which significantly improves the
asteroseismic output. Driven by this great potential, we carried out multi-site
observations aimed at detecting solar-like oscillations in the red giant stars
in the open cluster M67 (NGC 2682) (Stello et al. 2006). Here we present the
first analysis of our data, which show evidence of excess power in the Fourier
spectra, shifting to lower frequencies for more luminous stars, consistent with
expectations from oscillations. If the observed power excesses were due to
stellar oscillations, this result would show great prospects for
asteroseismology in stellar clusters.
