Tin Pan Alley, the home of George Gershwin, Irving Berlin and other great American songwriters, is up for sale. Five buildings on West 28th Street in Manhattan's Chelsea district are being offered as a group for $44 million. A listing on real estate Web site Loopnet recommends that the buildings be torn down and a high-rise take their place. Preservationists and tenants aren't happy... Tin Pan Alley housed a concentration of music publishers and songwriters from the 1890s to the 1950s.
