stage located about SSE of the site of the 1969 stage. (The site of the original stage is vacant except for a commemorative plaque which was placed in 1984.) In June 2008 the Bethel Woods Center opened a museum dedicated to the experience and cultural significance of the Woodstock festival. Notable events since the opening of the center have included an August 2006 performance by Crosby, Stills, Nash & Young and the scattering of Richie Havens's ashes in August 2013. In late 2016 New York's State Historic Preservation Office applied to the National Park Service to have , including the site of the festival and adjacent areas used for campgrounds, listed on the National Register of Historic Places, and the site was listed on the register in February 2017. Woodstock 40th anniversary There was worldwide media interest in the 40th anniversary of Woodstock in 2009. A number of activities to commemorate the festival took place around the world. On August 15, at the Bethel Woods Center for the Arts overlooking the original site, the largest assembly of Woodstock performing alumni since the original 1969 festival performed in an eight-hour concert in front of a sold-out crowd. Hosted by Country Joe McDonald, the concert featured Big Brother and the Holding Company performing Janis Joplin's hits (she actually appeared with the Kozmic Blues Band at Woodstock, although that band did feature former Big Brother guitarist Sam Andrew), Canned Heat, Ten Years After, Jefferson Starship, Mountain, and the headliners, The Levon Helm Band. At Woodstock, Levon Helm played drums and was one of the lead vocalists with The Band. Paul Kantner was the only member of the 1969 Jefferson Airplane lineup to appear with Jefferson Starship. Tom Constanten, who played keyboard with the Grateful Dead at Woodstock, joined Jefferson Starship on stage for several numbers. Jocko Marcellino from Sha Na Na also appeared, backed up by Canned Heat. Richie Havens, who opened the Woodstock festival in 1969, appeared at a separate event the previous night. Crosby, Stills & Nash and Arlo Guthrie also marked the anniversary with live performances at Bethel earlier in August 2009. Another event occurred in Hawkhurst, Kent (UK), at a Summer of Love party, with acts including two of the participants at the original Woodstock, Barry Melton of Country Joe and the Fish and Robin Williamson of The Incredible String Band, plus Santana and Grateful Dead cover bands.
