Johnny Cash‘s friends and family — including three generations of Cashes — gathered in Nashville on Tuesday (Feb. 14) for an announcement about the launch of the Johnny Cash Museum. The museum will be located in downtown Nashville on Third Avenue South, between the lower Broadway strip and the Country Music Hall of Fame and Museum and the city’s new convention center which is scheduled to open in 2013. Museum founder Bill Miller, a longtime Cash friend and founder of the JohnnyCash.com website, said the facility will occupy 18,000 square feet and will include artifacts, documents, video footage and other memorabilia collected by Miller and loaned by family members. Miller said it is also scheduled to feature a museum store and a performance area for special events. Phase one of the museum is scheduled to open in the summer of 2012.
