There is this odd Salem thing going on.  Some people like to say Salem should be pronounced “So-Lame.”  In this instance, I think it’s more a cross between sublime and strangely wonderful.  About a dozen old pianos have been placed at random locations around town with signs that say “play me.”   Roxanne and Susan came out to the one at Minto-Brown last weekend to hold forth.  Lizzie seems to be vocalizing while Roxie and Charlie are involved in some sort of original choreography.
