If the long holiday weekend has filled your head with warm and fuzzy notions of Pilgrims sitting down to dine with Native Americans in perfect concord, think again. I am guest host on “Sunday Morning Opera with Sandy” today, and we are listening to Howard Hanson’s “Merry Mount.” An adaptation of the Nathaniel Hawthorne short story, “The May-Pole of Merry Mount,” the work is an at times hallucinatory study in fanaticism, sexual obsession and demonology. Enjoy that with your leftover turkey sandwiches!

It’s on right now, on “Sunday Morning Opera,” until 10:00 EST, on WPRB 103.3 FM and wprb.com.
