UV-selected high-redshift populations like Lyman break galaxies anchor models of galaxy evolution, but have been largely inaccessible to key measurements of molecular gas content and dynamics that only the millimeter regime provides. On rare occasions, these otherwise very faint objects are magnified by gravitational lensing to provide exceptional targets for detailed study. By exploiting the large footprint of the SDSS and using 1.2mm dust photometry as a guide, we have identified a lensed UV-bright star-forming galaxy whose CO(3-2) line emission is extremely bright and shows spatially resolved velocity gradients across all three images of the background source. We will discuss how our IRAM Plateau de Bure Interferometer mapping of this source can be used to understand the role(s) of molecular gas in fuelling vigorous star formation and accretion at high redshift, as well as (perhaps) to study substructure in the lens.
