Janis Joplin, indeed!

I first heard her at the Newport Folk (!?!) Festival, and was absolutely amazed. But the *best* performance of hers that I ever witnessed was as an unannounced guest with the Grateful Dead one night at Pepperland in Marin County, CA (just north of San Francisco). Janis and Rod "Pigpen" McKernan were "an item" at the time, and they gave us some unbelievable vocal-and harmonica duets.
