  NGC 4649 (M60) is one of a handful of giant Virgo ellipticals. We have
obtained Gemini/GMOS spectra for 38 GCs associated with this galaxy. Applying
the multi-index chi^2 minimisation technique of Proctor & Sansom (2002) with
the single stellar population models of Thomas, Maraston & Korn (2004) we
derive ages, metallicities and alpha-element abundance ratios. We find several
young (2--3 Gyr old) super-solar metallicity GCs, while the majority are old
(>10 Gyrs), spanning a range of metallicities from solar to [Z/H]=-2. At least
two of these young GCs are at large projected radii of 17-20 kpc. The galaxy
itself shows no obvious signs of a recent starburst, interaction or merger. A
trend of decreasing alpha-element ratio with increasing metallicity is found.
