So why all the fuss over a single jazz concert from so long ago? Well, the history of jazz has its own unique timeline, one that often defies analysis or prediction. Unsurprisingly, the JRC’s fabulous Carnegie Hall show has sold out Cadogan Hall on no less than four occasions already. Even the stage seating plan will be authentic. Rest assured, too, that Long’s soloists will be a match for their predecessors and that the majestic Cadogan Hall’s fine acoustic will enable them to play without amplification, as happened in Carnegie Hall on that historic night.
