What may be the most impressive private collection of rock instruments ever assembled gets its first public viewing next month. Indianapolis Colts owner Jim Irsay has spent a good chunk of his fortune amassing an array of iconic instruments that belonged to members of the Beatles, Pink Floyd, Eric Clapton, Jimi Hendrix and many other great rockers. Many of those are included in a display that will be viewable for free at New York City's Hammerstein Ballroom on June 3rd.
