   High resolution, high sensitivity VLA observations indicate a dramatic
   increase in the number of radio sources in high blue fraction clusters
   at z=0.2 relative to clusters at the present epoch. This apparent
   connection to the Butcher-Oemler effect indicates that whatever is
   causing color evolution in these clusters, may be stimulating excess
   AGN activity as well. Due to the relatively short lifetimes for radio
   sources, it is possible to catch these systems at a very interesting
   dynamical state. We propose to obtain ASCA observations to determine
   the X-ray temperature and possible multi-component state of the ICM for
   three extremely radio populous clusters.
