(Newport, RI) -- Rhode Island is reaching an agreement to keep the Folk and Jazz Festivals at Fort Adams State Park in Newport for the next four decades. Governor Gina Raimondo and festival foundation chairman George Wein made that announcement on Saturday. A renewed lease with the state environmental management department will allow the foundation to utilize the former Museum of Yachting building. This weekend's folk festival included a surprise performance by the band Mumford and Sons.
