weeks long. The band launched a US summer tour in July that culminated in another festival in upstate Maine. 60,000 people attended the It festival which featured seven sets of Phish music over two nights, including a set performed live from the very top of an air traffic control tower. A DVD film and PBS special was made to document the festival. It was the sixth festival hosted by the band. The event took place on August 2 and 3, 2003, at the Loring Air Force Base in Limestone, Maine, just miles from the Canada–U.S. border. 60,000 people attended, resulting in one of the largest Phish concerts ever. This was also their most-played festival venue (see also the Great Went and Lemonwheel). PBS was on hand to make a documentary of the experience. Phish was the only band at the event, performing seven sets of music over two nights, including a late night ambient set on top of the air traffic control tower at 2:30 AM after the first night's concert. Fans camped onsite in tents, creating a community of Phans that became one of the largest cities in Maine over the weekend. Phish played only sporadically after the summer tour, including a brief four night run in late November/early December to celebrate their 20th anniversary. The third night of the celebration featured an appearance from founding Phish guitarist Jeff Holdsworth, who had not played onstage with Phish in over 17 years. The group closed out the year with a four night New Year's Eve run in Miami, featuring a surprise appearance from Parliament/Funkadelic. Original song debuts in 2003 included "Round Room", "Thunderhead", "Mexican Cousin", "Pebbles and Marbles", "Anything But Me", "Seven Below", "Mock Song", "Friday", "Spices", "Scents and Subtle Sounds", "Discern", "Secret Smile", "Two Versions of Me", "Army of One", "Spread it Round", and "Crowd Control." 2004 After a three-night stand in Las Vegas in mid-April, Trey Anastasio announced on the band's website that Phish was officially breaking up for good following a brief summer tour. However, the band continued to debut new material throughout the year, opening their farewell tour with a new song titled "A Song I Heard the Ocean Sing" from their final album Undermind, which was released shortly after the breakup announcement. The tour's opening night was also broadcast in movie theaters across the country and eventually released on DVD and CD as Phish: Live
